Scut

[PussyCat]

Used frequently in teaching hospitals by junior residents and medical students to describe mindless and thankless errands, such as chasing down radiology reports, drawing blood, and staying on hold with public health -- anything which is heavy on the service and light on the education.
Apparently derived from scutwork, meaning the work of a useless person.

In certain parts of Ireland the word scut was used to tell off their children. Like [feck] is the softer version of [fuck]. Scut would have been used in this way as it was the softer version of shite. Being a lad from the West of Ireland this word was bandied about in my area quite a bit.
Scut would have been shortened from scutter which as any farmer will tell you is not a pretty sight out the backside of an afflicted cow (terribly bad liquid diarrhoea). So when your ma was saying youre some scut, you little scut, or come here you scut ya, she was calling you a [shit] or a [shite] but in the nice clean way. Not swearing at all was she!
Also is you were on the town for a night out and say, the food you ate turned out to be bad, you might find yourself sitting on the loo for a few days after evacuating your bowels at a tremendous rate you would have a dose of the scuts.
If someone is talking [shit] or [shite] in certain parts of Ireland they could be said to be talking pure scutter.

Scut seems to have regional variations depending where you are in Ireland. In Fermanagh it means a naughty child or someone who is mildly annoying. It does not have the negative overtones suggested by other posters

SCUT is short for South China University of Technology.It is the most famouse university of south China. Students there are boys mostly, they usually dont agree with the idea thatgirls in SCUT are girls. They like girls from South China normal University and Guangdong University of Foreign Studies.

A rough low life female with low morals and a huge sexual appetite. It is a composite word formed from SCALLY (English shortened form for Scallywag, or Rapscallion - a no gooder/criminal) and SLUT (Old Norse)...which needs no explanation.
