strike off

male masturbation -the parallel of striking a match against a rough surface to get a flame.

i just thought of this concept and remain totally puzzled why a brit hadn't thought of it??? -whats up witchoo guys??, thought you guys invented the language!? (just 'screwing' with you!!!)

joe couldn't get a 'taste' so he was forced to 'strike off'

there was no one to help john out, so he ended up striking off!
