I found someone on the ladder who nicknamed his Rotom-W Washington. Found it really funny.
In my case, I've been naming my Pokémon with funny or something-related names. Garfield the Landorus-T, Thragtusk the Mamoswine (Magic: The Gathering reference), Metabee the (shiny) Mega Scizor, Batman the Gliscor (not very original, but fought against someone's Batwoman, a female Gliscor, once, and found it funny), Godzilla the Tyranitar, Kabuterimon the Heracross (or the shiny Mega Pinsir), Chun Li the Mienshao, Hulk the shiny Machamp, Mr. Krabs the Crawdaunt, Usain Bolt, the (shiny) Deoxys-Speed (he seems to "wear" Jamaica's colors too, so...) and of course Stallmory the Skarmory, for obvious reasons.

I did nickname my Excadrill that (in Spanish, but still)!Mr. Driller (Escavalier) lol references. And it knows Drill Run (YES I KNOW EXCADRILL WOULD FIT THE NAME BETTER)
