Holyheysus
is a sexual act. Its when the man spreads his butt-hole and then the women squirts into the mans butt-hole, then the man stirs the squirt around in his butt-hole to make "squoot". The finale he then finger paints the "squoot" onto the girls feet and then licks it off.
I tried the holyheysus and it was a new experience for me, my favorite part was the finger painting.
