Our hallucinatory friend Syd, is an imaginative word for the underlying spirit of acid. Popularized by Eminem as slang for acid..."Try syd and get fucked up worse than my life is. My brain's dead, wait, I'm trying to get my head straight"
Our friend syd dropped by to say hello, and ever since then we've been trippin balls.

Abbreviation for Sydney, as in the city. Pronounced "S-Y-D", not "syd".

It is often used by Sydney rappers, and by African and Arab youth in Sydney.
