Sniffy box

A box full of random things that smell weird.

Did you know Jimmy has a sniffy box ? He has it full of random crap like toe nail clippings, arse fur from a dog and a pair of your mother's used knickers.

Stiffy by the Liffey

The Dublin Spire, a monument in Dublin, Ireland, which some see as a phallic symbol. The Liffey is a nearby river.

The government is going to build another useless monument like the Stiffy by the Liffey.

The Flying Stiffy

To have your woman spread out on the bed, then take a run across the room and jump naked, with your feet touching your ass and hands behind you on your ankles, all while sporting a hard on. Then land with full insertion.

Amanda was impressed last night when i ran across the room and landed The Flying Stiffy.
