Unlike yer brain...YES.
I guy crowded me at a foosball table we were watching. Pushed me out of my spot where I was standing while watching the foosball game. I pushed back. He got aggressive and I clocked him with a quick left. One of the foosball players even complimented me on my left hook. Just call me roadkill Tyson. Mike had a killer left too.
Then we chilled out and shook hands.
