look up any word, like fleek:
 
1.
When a female performs deep-throat fellatio on a man too soon after she has eaten and as a result she regurgitates or ‘boffs’ her stomach contents onto the man’s genitalia.
Matt: Sandra started sucking my wang while we were driving home from dinner and after I slammed her head down too far she boffed all over my cock. It was rank, I had to scrape all her dinner out from my boxers. I think I’m gonna have to dump the bitch.

John: Yeah, no relationship can survive a boff-job
