look up anything, like your first name:
2. one off
A quick (often anonymous) one time sexual act with another of the same or opposite sex which ends in climax.
Dude, I can't believe that had a one off with that cop to keep from getting a ticket.

Damn, you really had a one off with that hot soccer MILF behind the beer stand?

1. one off
1. To act quickly without much forethought.

2. To perform a task using as little effort as possible
Person 1: "Did you finish your report?"

Person 2: "Yeah, but I one off'd it. It's a C at best."
