The Twisted Sister

When you take a woman into a restaurant bathroom for a blow job, and right before you cum, you twist her around and cum directly onto the back of her head and into her hair. You then rub the cum into her hair like styling gel, and make her look like Twisted sister.

After I turned the girl I met at the bar around and gave her the twisted sister, I immediately sat down on the toilet and started taking a shit while she was still in the bathroom!!

Your sisters a mister

Worse than “ur granny tranny” or “ur brothers a mother”. Every time this is said, the victim will implode into a ball of guts then blast into a shower of blood.

Joe: “Your gay.”
John: “Don’t make me do it.”
Joe: “Do what, pussy?”
John: “You’ve taken it too far.”
John: “Your sisters a mister.”
Joe: *Implodes then blasts out covering the walls in a red layer of blood and guts*
