Obnoxiety

Slang term defining the act of obnoxiousness. Generally used by Brits or people with funny accents in an attempt to seem high brow.

Coined by the person upon whom Eliza Doolittle (from 'My Fair Lady") is based.

Two long nosed brits at the theatre:

Leopold: I can't believe that American woman behind us just queefed!
Ms. Darcy: I concur! How horrible. That woman is a complete obnoxiety!
Leopold: There! She did it again! Oh, I'm about to start a row!
Ms. Darcy: Don't, Leopold!
Leopold: Why in heaven not?
Ms. Darcy: Because... then you'll be the obnoxiety!
