posh man's wank 

Where a man wears a condom whilst masturbating, as opposed to catching the spunk in a tissue/ something similar. The word 'posh' is used to denote the expense of buying a pack of condoms for such a menial reason (to make the wank more pleasurable).

"I've still got some jonnies left over, I know, I'll have a posh man's wank."
