Zacking off is the act of masturbating in the shower using kiddy porn downloaded to an ipod or any other mobile video device. The device is usually placed in a ziplock bag to avoid water damage and being contaminated with bodily fluids.
Lee: Why does Zack always bring his phone with him to the shower?
Danny: Yea, I'm curious too since he takes 45 minutes to take a shower.
Lee: I meant do you think he's zacking off in there?
Danny: haha yea i keep hearing weird moans coming from the bathroom and when he comes out he has the look of satisfactied on his face. He needs to wipe that smirk off.
An absolutely foolproof way to keep minors from viewing content deemed "too mature" for them to watch.
Billy: "So I was trying to watch some videos for an M rated game, and I ran into an age gate, so I put in my real birthday. SOMEHOW it managed to figure out that I am 12. CURSE YOU AGE GATE!!!"
Bill: "Fucking age gate! *quick scroll* THERE! I was born on January 1, 1904. Fuck you age gate."
