Bovarian Balloon

This is the act of jizzing inside of a condom during sexual intercourse, pulling out, blowing up the condom like a balloon (with the cum still inside of the condom) and popping it in front of the girl's face

Man 1: Yo! I heard about what you did last night! Did you really give that chick a Bovarian Balloon?!
Man 2: You heard right, dawg! Jizz went everywhere. So much better than a facial.
