To have three feet instead of two.
Person 1: "I have one more foot than two feet."

Person 2: "That means you have three feet."

Get the Three Feet mug.
When taking the ball out the defender can say, "check" (throw me the ball, and I'll give it back... typically to make sure everyone on defense is ready)... If the offense (guy taking the ball out) says, "three feet, no check" before the defender says, "check", the defender don't get to check the ball and he/she needs to back up at least three feet.
Jon took the ball out of bounds and yelled, "three feet no check!".

Get the three feet no check mug.
This term is used a lot when playing street basketball to imply that you shouldn't get to close to the person you are trying to block. Me and my friends say it when someone you're talking to gets to close to you or is invading your personal space.
A girl is at a bar and a guy walks over to her to make a conversation by getting really close to her face with his face and his breathe really stinks.

Guy:"Hhhhhey beautiful. Hhhhhhhow are you tonight?"
Girl: "Hey man! Three feet no check!" (As she puts her hand out and pushes him out of her face)
