Millennium Dome 

An expensive, ill advised, universally hated, embarrassment that you wish would just disapear.

It's all gone dome shaped.

Don't mention the dome.

Millenium Dome 

A slang word for a wonder bra. This is because it looks big and impressive from the outside and will cost you a fortune to get inside it. But once you actually get inside nothing else awaits but disappointment!

Millenium domes 

In a nutshell a 'wonderbra'.
Looking from the outside everything looks big and exciting, much like the millenium dome.
But once inside you're massively disappointed, and soon realise that it's nothing you're going to be writing home to your mates about.

Bloke 1: Epic knockers!
Bloke 2: it's a farce, they're millenium domes.

Tits that look good from the outside, turn out to be nothing but fried eggs underneath the push up bra.
