anyone know where the phrase **** on comes from? as in exactly right or fitting perfectly. i'm sure it's not rude - maybe something to do with taps or stopcocks?
One meaning of the word, dating back to the 1700s, was the target curlers aim at. Perhaps it was used to mean 'target' in other activities, too. As a result, if something is said to be "male-bird on", it means exactly right or spot on. (I use male-bird as an acceptable substitute and deplore - yet again - the totally absurd censorship that necessitates its use.)
