I highly doubt 99% of the people here would actually throw a punch in the case of a fist fight. In terms of who would probably be the only ones not hesitant to do it; Bisjac, Visage, Otis, Boltster, myself, Shinji and some other people I can't think of. It'd end up being the most socially awkward convention ever, you'd have the people with confidence talking up storms with some people, and then you'd have the remainder who are bitchy little women like MegaScience, Iban and Ike who would just ruin it.
Mega would reek up the place and make it all greasy and gross
Iban would try and threaten a girl to forget him otherwise he'll kill himself, thus resulting in cops showing up.
Ike would just open his mouth and people would dispurse.
