I am a college kid and was at a party where many kids were drinking underage, including the kid I punched. His friend threatened to "punch me in the face" and many other kids began to approach me and my other friend. The kid I punched proceeded to come up behind me and pour a beer over my head. My knee jerk reaction in the situation was to turn around and punch him. After that me and my friend walked away as the kid and his friend proceeded to yell at us.
