When Jane found Artie in bed with her best friend, Steve, she unloaded her .38 revolver into Artie's chest and bobbited Steve with the penknife she that was on the nightstand.
pimp: Yo ho get yo ass in my car right now or ill mess you up so bad yous be eating out a tube
ho: shut yo mouth no one talks to me like that. If you ever do that again i'll bobbit you.
A spliff that has not been tapped down enough after rolling, so that when it is held by the roach the rest of the spliff droops down, giving the appearance of having been been cut off and sewn back on again.
Named, of course, after the (in)famous John Wayne Bobbitt.
Bobbitting is especially common when backrolling, as the single layer of paper lacks rigidity.
