A San Francisco pillow fight consists of a group of skinny-jean and scarf wearing dudes taking turns flogging each other with their yam bags. The victor is determined by whomever can withstand the most scrotes without blowing their nut guppies all over the place.
Oh man, I was involved in the most intense San Francisco pillow fight, the other day. By the end of it, it looked like a Cinnabon store exploded!
