I punched a guy my senior year in HS during a soccer game that we were both playing in.
It was "senior day" and we had a girl on our team (no girls team). She usually played with the JV team but the coach put her in because it was senior day. We were winning like 3-0 and she got the ball, the dude on the other team lowered his shoulder and just laid her out, her feet flew over her head and the whole deal. She immediately started bawling.
All happened right in front of me and I immediately punched him directly in the face. Didn't even think about doing it, it just happened.
Got a red card for it.
