Omelettes are bog standard fayre tbh. Peasant food, if you will. Something you'll throw together if there's nothing better available but you'd have to be a bit of a cock to actually get excited over them.
Omelettes are the sort of thing your female flatmate makes while your staying at Uni. Men don't cook omelettes.
The hard way, aye Rather than getting yer knot popped wouldn't it be easier to just ask a fellow if he's gay?
