The thought process involved with the act of masturbation when no material (pornography) is available for immediate use. Typically when a male fantasises about a work colleague, friend or celebrity while stroking his meat.
Requires a certain amount of imaginative power - a weak mind could lead to loss of erection, or failure to gain it in the first place.
Frank: Oi, Steph was lookin' bang tidy last night eh?

Dave: Ah yeah, I had a good hard pornder about her while I was home alone this mornin'. One of the best wanks I've had in a long while.

I often pornder about the MILF next-door.
