The first time a food fight happened around me was the last day of 7th grade, first year of Junior High. I didn't know wtf was going on, so... I dunno my head down onto the table... and everyone else ran to the walls.
I was the one kid sitting there, half covered in someone's lunch, basically crying because I looked so handicapped.
I was only within like 2-4 more, which by the end I just looked around calmly, got up, and walked away. I'm a battle-hardened soldier, ya'll.
