Haha. I was gonna mention the phrase "danger wanks" but you
beat me (off) to it. Fnarr fnarr.
A danger wank when you're working offshore (or wherever) is when you have a quick one before your room mate comes in. No locks on the doors. It's a race against time and complete and utter humiliation for the rest of your career at that particular installation, and the entire oil industry.
And yes, we did used to find jazz mags hidden in the bushes when we were young. Fuck knows who left them there. I feel guilty that I've never bought any and left them lying about for the young 'uns to find, but that's the internet's fault.
Thanks for the kind words, Evey.
