A very small meal consumed shortly after a "normal" meal that didn't quite fill you up enough.
Let's stop at a fast food place for a top off meal...just something small. That last meal wasn't quite enough.
When you're jacking off and you can't finish so you call in a homie to finish you off.
Yesterday I was jacking off in my room, and I couldn't finish until I had John give me a Vienna Top-off
Some gay ass phrase my brother says cuz he thinks he's funny
"Yeeee! Top off the benz"
jumping off a high place, meaning suicide off the top, used in a joking way. no harm done, usually used when playing games.
*context; in a hill, tower, about to drop down, or just any high place* playboikobe: AYY SUEY OFF THE TOP BOYS!!
