A term used to describe a person or the act of chronic masturbation. To be described as a boff, one must be caught frequentlymasturbating in private, or in public.
A contraction of the two words "be" and off", commonly spoken aloud while in the act of leaving somewhere with a group. Can also be used while alone, but not aloud - only in one's head.
"Hey man, Craig just texted me saying that we can come over."
"Finally! Let's boff."
"Yo guys, him and I are gonna boff for now but we'll be back later."
