I was brought up knowing what Mardy meant, and it was in common use.

I moved all of 8 miles and when my sons were at school, they were accustomed to hearing Manny instead, meaning the same.

I did write a topical parody once many years ago with mardy in it, but be buggered if I remember what, where, why.   I do recall performing it at the time at The Boundary, Worksop though.

Ridiculous terms of abuse? I remember Tony Capstick having the BBC in a tizz when they wanted him to perform on Top of the Pops and they had issues with the word Wassock.

My favourites have always been Breadhead, duckspunk, Tha's like a one legged bloke at an arse kicking content and that old favourite, Miss Great Britain 1924.
