Bus a nut spelled backwards. A clever discreet way to describe ejaculating in or around a womans mouth/vaginal region.
All I remember was after she came out of the room, she wasnt hungry. She told me she got a tuna sub from Christian.

A trick where a person tells you ,"Say tuna sub backwards!". Being the retard that you are you will scream "BUS ANUT" (Translated: BUST A NUT), and everyone will start laughing at you and not with you.

Tuna sub backwards is "bus a nut". Men use backwards tuna sub when they're too ashamed to admit during sex that they're going to climax much quicker than they had previously thought.
Johnny: "Oh no! I'm about to backwards tuna sub!"
Jenny: "It's only been five minutes! Pull out now, you loser!"
