a posh wank - Wanking with a condom on because you're too lazy to clean up

Wanking with a condom on because you're too lazy to clean up but still too posh to be seen wanking in the street.

I wanked in my fancy suit with a condom because I didn’t want my socks to smell.

I wanked with a condom like I was on a date with my mom.

I wore a condom so my wank would look like a proper meal.
