The Applause 

There are two females and two males involved. Each female has four on the floor facing opposite directions. Each male is on his knees back to back. Both males simultaneously pork the respected females from behind. The clapping sounds made from male to female and male to male (thats why your back to back) creates an applause.
Warning: do not try with clap-on lamps

Bro, "the applause" we got last night was fantastic.

Applause From The Back Row 

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.. >.>

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.
