When performing a H-clap a female is giving a blow job to a male while she is recieving it from behind by another male. During this sexual activity the two men clap hands over the top of the female. The only way this activity is truely considered a H-clap is if the two men slap hands.
My buddy and I were H-clapping this chick at a party and before we clapped hands people just thought we were doing an ordinary eiffel tower, but once we clapped everyone cheered.
