When one ejaculate into a fat person's armpit. Then the person will lay their arm by their side until the semen dries. Finally the person will attempt to lift the arm, ripping the skin while blood mixes with the semen. Image resembles a strawberry shortcake and the outcome is very tasty.
Josh- Sup man, how have things with your family been going?
Andy- Not so hot dude, my mom still can't move her arm since my giant fag of a brother Evan Moist Armpited her.
Josh- Wow that blows, but is also FUCKING AWESOME!
