1.
When a man is doing a woman from behind and his balls slap her ass so fast it sounds like applause.

Girl One: Last night while I was having sex with him I could swear I heard clapping!

Girl Two: Yeeaaa... You were getting applause from the back row.. >.>

When you're having sex and your balls slap your bitch's ass so hard it sounds like clapping.
Guy: Bitch that was the best fucking sex ever.
Bitch: Yeah I know, I think even the neighbors were clapping!
Guy: Bitch, please. That was an applause from the back row.
