When you and a white male friend have sex with the same girl at the same time. As you are fucking her and she is giving him head, you reach across her and give him a high five signaling that it's his turn to fuck her. It's like when a wrestler tags his partner into the ring during a tag-team match.
a move involving two couples having sex at the same time and in the same room, ideally. After round one, the men get up to go to the other bed; they meet at the midpoint of these two ladies beds, high five, and shout 'Switch'. then the sex continues for round two with a new partner. repeat as needed.
Ashley: 'after this we should high five and switch!'
Chad: 'I think i tired Ashley out to much for round 2.'
