Here's a few that i have used often...

Umbreon - Twilight
Muk - Gravy
Exeggutor - Coconuts
Ninetales - Soulflame
Jynx - Lady Snow
Weezing - Chemikal
Sandslash - Sandro/Sandra (depends on gender)
Lapras - Mysts

Typlosion/Charizard - Firestorm
Vulpix - Vicky
Jolteon - Flash

I've also named a male vulpix after myself once and acted out "battle" faces, while i was hyper and bored. And i have attempted to make a team based on my best friends
