Taco Bell Tacos. While not that useful in a fight, eat to many of the damn cheap things and no one will want to be around you. Keeps everyone from being close enugh to hurt/rob you, plus if they hit you in the stomach, you can throw up on them. Hydroc. Acid! Puke on their faces or weapons. The Burning... THE BURNING!
I was going to say chopsticks, someone beat me to the punch.
