Sinead

Sineads are a type of girl who some people will like and others wont. she is amazing and friendly and usually very athletic. Sineads are usually small but good fun and have a good sense of humor. they are good at everything they try, especially sports. People tend to talk about her behind her back but she doesnt let it get to her. sineads seem to hit rock bottom more than anyone else but they get back up again.

'Wow, i met this girl today, she was so good at sports and laughed at everything. i think i'm in love!'
'I bet her name is Sinead.'
'How did you know?'

Sinead

A Sinead is the maddest, freakiest, wildest raver there is.
Originating from the North West of England, since 1987 this name has been heard frequently around the Warrington area.
A Sinead is not as quiet as you might think.
First appearances may be decieving!

Mate, she is such a Sinead!

Sinead

Someone who defines themselves. A complete whore.

The subject would say:
'a really cool girl. they generally have a love for emos. can be found in most scene places. they are good looking and have a great sense of humour and personality.
they are generally the radest girls around"

I mean who does it?

In speech one might say: Its as annoying as a Sinead up me hole.
