Nauseating: (Adjective) Of something which makes someone feel sick.

Katy Perry was forced to leave the Brit Awards last night (as seen above) after vomiting backstage. Not even for being a drunken idiot, which is what you'd think, either. Apparently Katy was just legitimately sick.

And Perry explained her illness to the audience: "I'm so sick right now, but they said I should show up because something special might happen. Thank you to everyone at my record label. (I proved) I work pretty hard because I want to die right now." (Source)

No word yet on what caused her illness, but my theory is that it had something to do with her entire corset being covered in Hello Kitty. I know I had to fight back chunks of half digested English muffin just looking at it.
