Founded and innovated by Tommy Page, the phrase STGU was used as a way to combat people who used the word STFU as it got to be too annoying for anyone to give a shit about. STGU (Shut the Gay up) was born, which means "stop acting gay" or "stop with the gay shit". In nerima, being gay is a very -negative- thing--it's like being retarded.
