Mom: Son, you have another phone call. Do you want me too tell them your eating diner?
Son: Yeah just tell them I'm mastacating! They'll deffinatley stop calling
"I grabbed a steak and almost stuck it into my heart to commit suicide."
"Snap was spying on me and he was taking a video tape of me! And Loopin was masticating to it!"
The equivalent of a cock block, but when it happens during solomasturbation. Someone knocking on the door while a man is jacking off inside would be masturhating.
Jon: So what'd you do yesterday man?
Alex: I was bored as shit so I was just jacking off until my brotherknocked on the door. Totally masturhating.
