Co'Co'

UIC notation for a locomotive with two bogies with three axles each, all powered by one motor in each bogie.

Also railway slang for a broad with nice big boobs and nice ass. Bo'Bo' is a more modest.
Two rail enthusiasts are waiting for the train, drunk after a party.

Rail enthusiast 1: Dude, check out that Co'Co' over there! I'm gonna hit on her

Rail enthusiast 2: Yeah, you do that while I feel up this Bo'Bo'
