SFSU

The best school ever. Constantly smells like weed and the on-campus market is filled with kids with munchies past midnight on the weekends. Full of hipsters and full of culture. Everyones is friendly and the Village DSA is where people are social.

The people who go to this school are either very local or from SoCal and have never used the expression 'hella'.

It's basically in Daly City and only in SF because that's the name of the school. Close to the beach and close-ish to the city.

Anyone who goes to SFSU is awesome.

SYFFUF

SYFFUF is short for "Shut your fucking face, uncle fucker", a commonly used phrase in the USA. It was introduced in 1890 by Pope Gregorius XIV but gained popularity when Matt Stone and Trey Parker used it for a song in their popular television series "South Park".
