Sumner Hinch 

While in sexual intercourse with your male partner, run at him as fast as you can ramming him in the ass yelling, "Ten Points Gryffindor!" then ejaculating in ones belly button.

Man 1: Here I come Sumner Hinch!
Man 2: Ugggggh!
Man 1: Ten Points Gryffindor!
*pffft* ejaculates in belly button
