Cathy heard about buttsex on HBO, but thought she had to get arrested before having it. We haven't seen her in four months.

the act of sticking your wanger inside someones buttwhole whether it is a girl or guy and letting out a substance called buttcheese inside their anal whole.
Ike became very tickelish and started to giggle as paul began to stick his penis inside Ike's anal whole. When paul called for buttsex, Ike replied YES PLEASE!Hopefully it's better than what my parents said how it felt...
