Shwack is another way to say masturbate. My friend is named Shwack because he shwacks a lot.
i shwack two times in the morning, i shwack two times at night. I shwack two times in the afternoon, it makes me feel alright. I shwack two times in time of peice and two in time of war. I shwack to times before i shwack two times and then i shwack two more.
