"Off my leg"

The BYU humanities department used to have this international movie theater where you could go see edited for consumption intl movies for about a buck. It was a fairly popular place since it was cheap and the lines were long. I remember one time we went to watch some french maiden movie, Manon of the Spring or something similar and were waiting in line, probably being obnoxious and accidently pushed the velvet ropes of the line onto someone. I remember in a clear distinct voice someone bellowing out "OFF MY LEG", of which we couldn't comprehend. I look around and the mantra "OFF MY LEG" occurred again. I look around and noticed the velvet rope was on this guy and that for the life of me I couldn't figure out why he didn't just move the velvet rope himself OFF HIS LEG. Instead we had to remove it for him. He was clearly offended that we had invaded his space. OFF MY LEG became part of my lexicon moving forward, signifying frustration or irritability. The guy probably ended up dying of a heart attack at age 35 because of stress.
