The phrase smells like a manufactured idiom (i.e., no idiom at all) which means to 'Get out of here!'The model for this is 'Beat it!'. It means that one should beat an egg in one's shoe by moving their foot (toward the exit). As far as I know the only use of this so-called idiom was on a Saturday Night Live sketch, featuring Michael O'Donoghue as a nasty bartender at a roadside bar, dispensing cruelty to a boozy Laraine Newman. Newman is a whining woman who asks O'Donoghue for advice. He says: 'Put an egg in your shoe!'. Newman (puzzled): 'Put an egg in my shoe? O'Donoghue: 'Yeah... put an egg in your shoe--and beat it! ' O'Donoghue probably wrote this 'idiom' himself, as one of the writers of the show. He was that kind of guy.
