I love finding names for my pets, but a lot of them are pretty generic or boring because I can't be bothered to think up a very creative name for the tenth cockroach when I hate bugs.
That said, Lots of wow references in mine:
Onyxian Whelpling - More Dots
Spawn of Onyxia - Stop Dots
Death Talon Whelpguard - Many Whelps
Dragon Kite - Handle It
Vampiric Batling - Animal Wing (after that crappy part of Kara no one ever did)
Phoenix Hatchling - Merely A Setback
Fel Flame - Not Prepared (Spark of Azzinoth was too long
)
Wildhammer Gryphon/Gryphon Hatchling - Beaky (After the baby gryphon from the quests in Twilight Highlands)
Hopling - Buntallus (I remember doing progression raiding on Brutallus back when hitting 2k DPS was pretty impressive. XD)
Brilliant Kaliri - Falling Damage (Anyone who did Skettis dailies back in BC will remember the Kaliris and the fateful day Blizzard let them learn how to fly upwards.)
Lizard Hatchling - Gezzarak (because it's the purple/yellow skin like the summoned warpstalker boss in Skettis. She was also the only warpstalker with that skin for a very long time.)
Curious Wolvar Pup - Kekek
Curious Oracle Hatchling - Roo (Because those were their names in game.)
Minfernal - Legions ("You face not Malchezaar alone, but the legions I command!")
Tundra Penguin - Lil Dippy (After Dippy from Brawler's Guild. He just wants a hug. And to eat your delicious, delicious eyes.)
Corehound Pup - Runty (After the small pup in the Beauty encounter in Blackrock Caverns that, if killed, would cause Beauty to engrage and eat everyone's face off.)
Mini Mindslayer - Sweet Cheeks ("I'm gonna light you up, sweet cheeks!" The Arcatraz was a really hard heroic in BC, but I always loved Millhouse Manastorm in it. I always thought he was just somehow wrongly imprisoned or accidentally ended up there, too, not that he was actually a bad guy
)
Personal World Destroyer - Lil Fel Reaver (Not terribly clever, but I was so incredibly excited when this pet was added to the game because he was the exact thing that I'd been talking about with friends as an idea for a new mini pet back in Wrath. I still think he should make the sound the Fel Reaver makes, though. Anyone who played in BC would jump every time they heard it. >_>)
Jade Owl - Scree (Back in BC my husband's raid had a hunter who really liked to bring an owl to raid and at the time it did it's vocalization almost constantly which was a loud SCREE. Thankfully they nerfed the scree, but Husband and I still joke about it to this day.)
Searing Scorchling - Lil Geddon
Lumpy - Lil Gar
Harbinger of Flame - Minordomo
Fungal Abomination - Liltheb
Untamed Hatchling - Razorsmall (After Razorgore)
Stitched Pup - Precious (And my husband named his Stinky for the matching pair)
Viscidus Globule - Reak (After a rare of similar model in Hinterlands)
Gregarious Grell - Viel (After the imp who sold an item needed for the now-gone Dungeon Set 2 questline.)
Landro's Lichling - Mildly Annoyed (Round-about reference to Rage Winterchill)
Jade Tentacle - Lucid Dream ("I am the lucid dream. The monster in your nightmares. The fiend of a thousand faces. Cower before my true form. BOW DOWN BEFORE THE GOD OF DEATH!" Yogg is probably still my favorite boss fight of all time. My husband named his jade tentacle "Hatred and Rage" in a similar theme.
)
Lil' XT - New Toys
Landro's Lil' XT - So Tired
Clockwork Gnome - Miniron
Proto-Drake Whelp - Razorsmall (After Razorscale)
I did a theme with most of my dragons to have their names starting with "mini"
Frosty - Mindragosa (BETRAAAAAAAAYS YOU)
Scourged Whelpling - Minimyst (Not skeletal but an undead dragon all the same)
Emerald Proto-Whelp - Miniscale (After Razorscale)
Nether Faerie Dragon - Minispite (Not the same model as Netherspite, but nether like him :3 )
Infinite Whelpling - Minizond
Nexus Whelpling - Minygos
Lil' Tarecgosa - Minicgosa
Dark Whelpling - Minifarian
Azure Whelpling - Minigos
Emerald Whelpling - Minisera
Crimson Whelpling - Ministraz
Crow - Hotfix (Because it was, in fact, hotfixed and because I spent, like, four hours to find a rare that day. ~_~ )
Black Lamb & Little Black Ram - Ram Ewe (because that spell name in game amuses me to no end.)
Strand Crawler - Ghostcrawler
Mulgore Hatchling - Lil Mazzranache
Gundrak Hatchling - Bitey (After a quest in the Wetlands called "I'll call him Bitey")
Out of game references:
Clockwork Rocket Bot - Envy (because for years I was envious that my husband had this pet and I missed getting it by a couple months. This was before it was added back into the game.)
Tiny Bog Beast - Alec (The guy who became Swamp Thing's name)
Magical Crawdad - Rock Lobster
Darkmoon Rabbit - Dynamite
Sandy Petrel - Seagullsicle (I'm surprised I didn't do more Python references, to be honest.)
Oily Slimeling - Beepee (Husband's suggestion because of the BP oil spill)
Various Turkeys and Chickens - Lunch, Dinner, Brunch, Takeout
Emperor Crab - Citizen Snips
Baby Ape/Bananas - Donkey ("I know that monkey! His name is Donkey!" "Monkeys aren't donkeys, quit messing with my head!")
Nether Ray Fry - Philip J
Fledgling Nether Ray - Symposia (Husband and I always found it incredibly amusing that Fry knew the correct plural of Symposium.)
Yellow-Bellied Bullfrog - Welshie
Venus - Seymour
Clouded Hedgehog - Sonic
Imperial Eagle Chick - States (Both a reference to the US's national bird and a character from the now-defunct MMO City of Heros)
Nordraaail Wisp - Hey Listen
Pet Bombling - Bob Omb
Various Bandicoons - Tom Nook, Tim Nook, Todd Nook
Alpine Foxling - Fenrir
Gilnean Raven - Munin
Wild Golden Hatchling - Gold
Wild Crimson Hatchling - Ruby
Wild Jade Hatchling - Emerald (While I didn't actually play those pokemon games I felt the opportunity to pay homage to them was too good to pass up.)
Tiny Twister - Thunderus
Terrible Turnip - Ash (Husband's suggestion since he's the one I use for catching all the things)
Arcane Eye - Visine
Clock'em - Robbot Paulson (Since the whole of brawler's guild is a reference to Fight Club this felt appropriate.)
Pandaren Monk - Bill (I like the Kill Bill movies more that I probably should.)
Giant Sewer Rat - R O U S ("I don't think they exsist.")
