z blow

1. A fast powerful uppercut to the stomach that makes a thunderous sound upon contact. Originated from hard punches that were from DBZ.

2. A hit (usually a uppercut to the stomach) strong enough to end a fight in one hit and leaves the receiver writhing in pain.

Justin: "Just give him a z blow to the face and he'll shut up."
