where i from in tha UK we say we gonna go get "wrecked" if we gonna be goin out to get completley drunk!!! but yea we say gettin pissed as well
we also say goin get to leathered to mean goin to get drunk...but to get leathered also means to get a good beating
taking tha piss means to make fun of someone...but we also call that jesting...but we also use taking the piss to mean like taking advantage of someone or of their gud nature...so like u borrow £5 n then ask for anotha £20...thats taking the piss!!!!
