A friend and I started calling each other 'Chod-Head' in
1985. It is a derogatory term in general and not too specific (
like many minor profanities).We thought we had made it up but many people in our place of work (about
8000 at the time) started using it.
'He's a complete chod-head' meaning dick head or
stupid git.
'He's a total chodder' meaning that he can't do anything right.
'You're a raging chod'
However they came later
CHOD HEAD was the original statement and came in total
exasperation of anything else to say about the man we were describing.
