A combination of the words "pissed" and "can't." A pisscant is a person who has problems in their life, but rather than trying to fix them, explodes in anger on something completely unrelated.
Mark hates his job. Though rather than confronting his boss or quitting, he yells at and beats his wife and kids. He's a pisscant, and I don't like him.
