Sometimes you need to re-frame things in terms people can relate to.
Last weekend, whilst having gone bush, one semi-drunken conversation lead to another and the topic found itself lurching around to dogging. Now you have to factor in that dogging is not a widely known term (or activity) in Australia, and the woman trying to explain the phenomenon was a) tipsy and b) almost incomprehensibly Irish. The conversation turned to the complicated system of car headlight codes that mean you can watch, you can join in, or you can feck off you ugly bastard. (As she put it.) One of the members of the university faculty (and fellow homosexualist) was struggling to get a grip on the concept.
Until I turned to him and said "It's a beat (cottage/tearoom)... for straight people."
