clap off 

When two couples have sex in the same room and it either becomes or starts out as a competition to see who can last the longest

Person 1: Yo did you hear Dave and Press had a clap off?

Person 2: No I didn't, really?

Person 1: Yeah Dave had a girl on his bed and Press had a girl on the futon.
