Suffix that can be applied to any noun to signify "it" is deeply hated by the speaker. The most effective use of "must die" lies in the modification of a person's name. Repeated use can impact complete restructuring of a person's identity.
1) "What, your platonic male acquaintance climbed into your bed while you slept and put his gross fat hand on you? Ok that's it: John must die."

2) "Hey you see that guy across the street in the blue cardigan? That's my neighbour Steve-Must-Die. You know, the one who says he's a DJ?"
