bebop
1. An early form of modern jazz.
2. The name of Spike and crew's spaceship in Cowboy Bebop (an anime).
3. The name of one of Shredder's henchmen (the mutant boar) in the Teenage Mutant Ninja Turtles cartoon (1980s) and anime (1996).
Bop and bebop are the same kind of music.

Bebop: I'm glad they didn't use that brain switcher thing on Rocksteady and me. 
Shredder: Don't worry, you can't switch something that isn't there.
