A variation on the teabag. A teaball involves 3 people, at least 2 males. Male #1 lowers their balls onto the mouth of Male/Female #2 (who is lying down). Male #3 then tries to hit the balls off using their penis. The activity is similar to that of childhood sport tee-ball, where the balls are the softball, and the penis is the bat.
First used in Toronto, Canada in late March, 2010.
"Vince and Jon were feeling adventurous, so instead of giving Keith a plain old teabag, they decided to sport it up and give him a teaball instead."
Dude I was on a teaball speedballlast night, it wall like a baby version of coke and heroin. I’ll probably move on to actual coke and heroin soon because it was dope.
