When a man thrusts his pelvis foward towards a woman/man in order for the other person to feel their "

This is not
always done intentionally. There is such a
thing as an "accidental peen press"
Kevin: "Dude Amy's fuckin
hot I think im gonna peen press her, 20 % chance she'll like it, 80 % chance she'll be offended"
Amy: "like... Kevin totally peen
pressed me and i didn't feel a thing...
awkward"
