Pronounced “Bunk”, it means bullshit, but is typically used to say you or another person is on some bullshit (said as “on bunc” rarely ever just used as “bunc”). It can be used positively or negatively.
Negative example:

Friend: aye bro, did greg ever pay u back for the uber?
Me: Nah nigga he was on bunc.

Positive:
Friend: yo we going out tonight?
Me: Yessir i’m on bunc i’m finna act a fool
