Half-Sack

Someone who either has only one testicle, or a man with the balls to talk some shit yet not willing to back it up.
Cody is such a half-sack! He called me a pussy and then rolled off in his wheel chair! I was able to catch him though. I moved him to the intersection by the bar and put the brake on so he couldn’t move.
