circus tits 

Excessively large, generally fake, breasts. Common in porn.

Jesse Jane's circus tits just don't do it for me.

When one breast is obviously larger than the other. Or one breast sags more. Basically a term for mismatched breasts.

Example: "I'm having trouble finding a bra that fits my damn circus tits!"
