One time I banged into a big guy on the way back from the water fountain, and he didn't say shit cause he could see I was a stone cold killer. And the old ladies on the treadmills better check their shit, they get a front view seat to me laying the smackdown on the heavy bag in the pilates studio before trying to do a max bench with 180 (and getting pinned), followed by lots of hostile 'who the fuck YOU lookin at' eye contact with everyone else in the gym.
