corpse, other than in the dead body sense, can be used to describe the way somebody looks or feels or the way something looks.
eg 1)Steve - what you cooking?
Rich - meatballs from a can
Steve - that looks corpse, i wouldn't eat that shit!
eg 2)Rich - you look terrible, did you drink a lot last night?
Steve - yea, i drank a fuckload, i feel like a corpse, i think i'm dying!
eg 3) Loz - did you see the girl i went home with last night?
Steve - yea she was a fucking corpse! did you get her number?
Loz - yea
Steve - i wouldn't bother ringing her haha
