Get the mardi mug.
Several examples have already been provided but 2 points might be of further interest:
1. The Nottingham writer D.H.Lawrence uses the word in his novels of the 1920's
2. Reputed to have originated from the French word 'merde' meaning 'shit'. So, to be 'mardy' would mean to be behaving in a 'shitty' manner.

I grew up in 1950's Leicester where it was in common use.
'She's gone all mardy'.

He's being mardy because he can't get his own way.'
