A group of self-centered bitchy freshmen girls from Walt Whitman High School known for being sluts, but are too ugly to get any. Origional name: Cult (Cute Little Underage Teens),changed when they came to realize that name was already in use. Despite the fact that upperclassmen is in fact ONE word this group of "elite" girls renamed themselves "Fuck U Upper Classmen."
The FUUC was totally hanging out in a church parking lot on Halloween night.
