I dipped my johnson in the school cafeteria mayo and mustard
Oh, no! Why'd you dip your johnson in the school cafeteria mayo and mustard?
I thought it would be a funny prank.
You sound very juvenile. It's disgusting to put your private parts in the school's condiments. I think you need professional help.
No one found out and it's really not a big deal.
You could get in a lot of trouble for putting your penis into food in public. With so many cameras in the world these days you could easily get caught and kicked out of school or even arrested.
