Burst sofa

n.

Heard in Dublin

A rather tasteless reference to a lady wearing crotchless panties.

In use

I came home early the other night and the missus was up waiting for me in a pair of crotchless panties, 'jaysus ' I said... ' it looks like the sofa burst'

Posh English

I returned rather prematurely the other evening to find my good wife awaiting me in altogether ventilative undergarments. Heavens, I remarked, it appears the settee has ruptured.
