When
something is boring, overused or generally shit it is referred to as 'shagged'
This often replaces the more commonly used 'gay'
e.g "man this algebra
stuff is gay, why do i need to learn this
shit?!"
Guy 1 : Duuude, drainpipes are so shagged
man. your such a
sheep!
Guy 2 : Dude! i so am not, it's cool
man.
Guy 1 : Whatever, they're shagged!
