Grattan wank 

Masturbating to the lingerie pages of a clothing catalogue, as you did when you were 13 and couldn't get hold of proper filth.

Also handy for when you want a change of pace from mind-blowing internet-based grot.

(The Grattan catalogue was popular in the Uk about 15 years ago, and had a huge ladies underwear section.)

"Dude, I went old school and had a badass Grattan wank last night"
