Dicked in the Nob

It's always rather amusing when a word once blameless now has a rude meaning, and a double example of this is dicked in the nob, which once meant silly. Nob used to mean head in C18th thieves slang and dicked... well dicked is a bit obscure, but the first recorded use of it to mean penis wasn't until a slang dictionary of 1891.

What we might now call a dick was, back in the C18th, sometimes referred to as a man's gaying instrument, where gaying meant happy-making.

I think I should stop there, only noting that, according to William Holloway's General Dictionary of Provincialisms, in early Victorian Yorkshire an ass-hole was an ash-hole.
