Who goes nogging the nog, and why?

The reason, Raak, that no-one has bothered to reply to your "Who goes nogging the nog" entry is that the answer is so obvious that we cannot bring ourselves to utter it.

Moving swiftly on... I used to think that Revolving Door was rhyming slang, but could never conceive of a rhyme that fit the context in which the expression was (with rolling eyes and nudges) used. Now I'm not so sure...

Hmmm - your secondary instincts may be spot-on . . . only because a 'revolving door' is an alternative [rhyming slang] yet polite way of describing a 'Roger' [bruising nudges, grossly exaggerated winks and embarrassing stretchy mouthshape] short for 'Roger Moore' - he of the questionable raised eyebrow and much else besides.

OK. What about this weight-lifting mallarkey then? I am told that a Clean and Jerk technique is desirable if one wishes to go from strength to strength?

Yes, "clean and jerk" is now a weightlifting term (to lift and successfully support the weights are two different levels -- one at shoulder-height, or the "clean", the other with arms straight above the head, the "jerk"), but it came from the original weightlifters -- Eastern European immigrant women to the US. They often had 10 or more children in the fambly (accent declared), and as such the laundry load was wont to be 100lbs or greater, so the mother had to do a similar technique to carry it.

The reverse term could also apply to the fathers after the 5th or 6th kid....

I was having a drink with a few friends from Physics when one of them pointed to a nice-looking girl, but said "he once gave her out for hitting the ball twice." Was I right in choosing to avoid her then?

Yes "hitting the ball twice " is a reference to somebody who when first met was fantastically beautiful and well turned out but after a couple of dates turns into a smelly unkempt wretched figure who you wouldn't look twice at. The phrase originates from the story of Cinderella who arrived at the ball looking like a princess but by the time she left had already lost a shoe and arrived home looking like a tramp, one can only imagine what a subsequent trip to the ball would have resulted in.

Moisten the sand and old Bedouin saying but what was it about?
