When you are banging a girl/guy and right before you blow you pull out and jizz into his/her bellybutton and then take one of fingers on your RIGHT hand and push it in and out of their bellybutton so it makes a noise.
I was banging that chick so hard last night and right before i blew my load in her I pulled out and gave her the old, grease hole and she loved it!
