To squat down on your toes, reaching under the leg to masturbate in a downward motion.
Common sport amongst contractors working away from home. Of an evening, should they be feeling frisky and risky, they may strip off, carefully climb up on to the B&B’s sink rim, tiptoes on the unsupported edge. Whilst in this expert position he may decide to crab-wank one out whist his face/eye is pressed against the mirror, eyeballing himself until completion.
Martin: How was your evening Andy?
Andy: Pretty tragic really.
Martin: But I thought you had your night planned? Kebab and a crab-wank you said??
Andy: The kebab was great and I was after a thrill before bed.
Martin: What’s tragic about that? Did you manage the expert?
Andy: Almost, but the sink came off the wall and I couldn’t finish.
Martin: Still, better than Steve last year, his sink shattered and cut his femoral artery.

Andy: Hummnn, I may go back to the floor for a bit…
