Tits On Toast 

1) An open-face fried egg sandwich, for obvious reasons. 2) A general purpose substitute expression for small inconveniences, used when stronger expletives are inappropriate(ie, 'shit!' or 'goddammit!').

1) (Waitress) "Hey Murray, I need a Number 5 and a Tits On Toast for table three."

2) Aw, tits on toast...my iPod battery died.

Tits on toast 

1. When a woman dresses seductively, particularly with a low decolletage or with a style that accentuates the cleavage.

"She usually doesn't make an effort, but last night she was all tits on toast!"
