Originally used to describe the suspicious day off 'sick' the fabled Disco would have after a heavy drinking session.

Phrase now covers any suspicious sick days, particularly when person was fine the day before and seems fine the day after.

Basically, you take a disco day when you can't be fucked to go to work.

Make's Dave's Disco Day and Disco Day look amateur at best.

Usually takes the inspired angle of actually coming into work, before setting up the need for extended holiday with a few well timed coughs.

I am in awe at her expertise.
Emma's coughing again - doubt we'll see her for the whole of next week - she'll be taking an Emma's Disco Day.

Brought to you from the makers of Disco Day and Dave's Disco Day.

This is a Disco Day taken from your place of work when everyone actually knows your not sick but for some reason just accepts that you're not coming in and does nothing about it.

The evidence of this usually stems from a physical injury sustained over the weekend which allows continued movement and general celebration throughout the weekend but prevents journey to and from your place of work.

The most audacious Disco Day so far.
Tom did a half marathon on Sunday and tweaked a foot muscle. He made it out on the piss on Sunday evening but hasn't been seen at work since. He must be in a great deal of pain to take a Tom's Disco Day.

A problem affecting people with genuine illness when their colleagues don't believe that they are actually ill.

Most often attributed to previous Disco Days being taken (as in the boy who cried wolf).

Results in frustration for the sick person.

Originated in Accountancy Practices in Bristol.
Dave had a stinking cold but all his colleagues believed he was taking a Disco Day.
