Weird words, and different sex acts!

What are the weirdest words and sex acts people have heard of? I'm not looking for anything really offensive more of the silly or just plain off the wall words or sex acts. For example: Blumpkin is getting a Bj while you are going to the bathroom, and Figging which is carving a hand of ginger into a buttplug and inserting it into the anus(of course).
