2.
Short for the phrase "suck a nigga off". It can be used as a descriptive pronoun, to a verb, or to describe the physical act of performing oral sex. It can be used as a one sentence question, or even a rhetorical question if the receiver understands the terminology and accepts.

Adding an -er to the word snoff can also be a semi-derogatory word for describing a young, brainless female who sucks a lot of dick, and who will most likely suck yours.
"Snoff?"

"I got some good snoff last night."

"Damn, girl you know how to snoff."

"That chick is such a snoffer."
