the beast with one back

To relieve oneself of carnal desire while experiencing personnel shortages..
To knock one out.
To unwind the clockweights.
The unloading of crew from the submarine.
To furiously masturbate.
"What a darned inopportune time to ring me,I was getting seriously aroused at the sight of J-Lo in this flashdance knockoff music video,and was about to make the beast with one back.....Now fuck off while i av a wank.
