A headless person.
Made a shoulder-like frame of cardboard with a hole in for my head, and put it on my shoulders. Then, put an over sized adult shirt on it.
Just slip the arms of the shirt under my chin and wa-la; headless person. xD
Looked pretty much like this w/o the blood xD :
Me and my two friends were major gangsters. We sagged, chilled in gigantic hoodies, "grabbed our twinkies and rolled", pretended to be drunk so good some high schoolers actually thought we were drunk guys..we tricked them too and they almost chased us back to our house..they got so scared..
