blumpkindred spirit 

A "new friend" found while cruising for sex in a public men's room. The new friend will perform a special sex act (a blumpkin) without even making the recipient get off the toilet.

Repugnican Senator Larry Craig sat down on the crapper and assumed his usual wide stance. He moved his foot toward the next stall thinking the guy next door might want a blowjob while he was taking a dump. He soon realized the guy was an undercover cop, not a blumpkindred spirit.
