gallagher

After ejaculating on a girls buttocks, the man takes his penis, and much like a hammer to a watermelon, uses the head of his penis to splatter his own pool of semen all over her.

Getting inspiration from the prop comic, Ted decided to give his girlfriend a gallagher, unknowingly hitting her cat who was in the splash zone.
