When you're so white girl wasted that the party* starts coming out of your nose, and you spend 40 minutes spewing in the bathroom leaving everyone wondering where you are.

*Typically your own party for which everyone's come to spend the night with you. (But they can't) (Cos you end up going home to spew some more)

The term is also often referred to as a desirable state for which white girls wish to achieve when "hitting the town".

Get a Mardi mug for your papa Manley.
Someone who is confident, self assured, and capable. This person is also wild, crazy, and a huge rebel. Always up to something. Likely to get in trouble. But your kind of trouble is a lot of fun.
People see them as stubborn and headstrong. You definitely have a dominant personality.
Lastly, they are a free spirit, unpredictable, adventurous, and always a little surprising.
That Mardy is a handful.

A person who is noted for being mardy – that is to say demonstratively miserable. Being depressed doesn't count – the mardy arse revels in unhappiness and broadcasts it via sulking, moaning, whingeing and (in the case of children) crying at the drop of a hat. An element of paranoia will generally be present; the mardy arse permanently feels hard done-to.

Perhaps the key difference between grumpy and mardy is that the former involves more anger and the latter more self-pity. However, in an almost bipolar way, the mardy arse will tend to be someone who mood-swings from mardy to lary – from surly/resentful to surly/aggressive – often when alcohol has been added as a catalyst.

The term is a coarser and therefore more emphatic version of mardy bum (the 'bum' in this sense referring to the buttocks, not a beggar or hobo, and 'arse' being a less polite word than 'bum'). It may be heard in the same Derbyshire, South Yorkshire, Nottinghamshire, Leicestershire zone of the English East Midlands where mardy is commonplace, though principally the city of Leicester.

Mardi Gras is French for "Fat Tuesday" Originally created in Mobile, Alabama but now made into amazing shit by New Orleans, Louisiana. Although Mardi Gras Day is the big day of celebration it is the days, or should we say nights, that are really celebrated. Random hookups, exposures of oneself, and complete and total memory loss and lack of judgement occur on these wondeful nights.
Only during Mardi Gras will you see a 12 year old smoking weed and a 10 year old drinking beer. BUt only in New Orleans are people actually use to it.
