Pissed is British slang for intoxicated, drunk.
drunk. (Not to be confused with pissed-off.)
This is a great one for misunderstanding. Most people go to the pub to get pissed. In fact the object of a stag night is to get as pissed as possible. Getting pissed means getting drunk. It does not mean getting angry. That would be getting pissed off!
