Shagging can be very helpful in the right circumstances. But more important at the moment is...just where the heck did that word come from to describe that act?

"shag (vb) to have sex (with).
A common vulgarism in Britain and Australia which is unknown in this in the USA. The word is an archaic relative of 'shake', which was used in a sexual sense from at least the 16th century. In Britain shag took over the taboo role in the 18th century, while in the USA it took on the (now obsolete) meaning of 'run off' or 'run after'. In modern usage the word is considered less offensive than fuck in male company, but more vulgar than other synonyms. Like fuck it occurs in other forms, such as the noun shag, the intensifying adjective 'shagging' and phrases such as 'shag off'. "
