Jul 12 Word of the Day
The horrible moment when you realise that you have accidentally done something very slightly wrong which has very bad (usually embarassing) implications for you. This is typically the moment of realisation that you just sent a dirty text message to a close member of family, typically your mother, rather than the intended recipient.
Message: "i'm free this afternoon so come over and fuck me senseless, my parents will be out all day"
Recipient: Mum

2. (N) The guy in the group who will run you over with his car, drop 300 dollars playing 25/50c poker, show off his 4 inch knife, send everyone you know a computer virus, then have a 3 some with Phil in the back of a van with some chick.

Zach:I heard Sleek was going to Iraq.
Ben:Ya same. I also heard he had a three-some with Phil

Originated a conversation with my 13 year old sister, who claimed that at her school (Newstead Wood), people were either "slags", "neeks" or "all right." Or they were neeks who were also slags- a common stereotype of the Newsteadians, perpetrated by people lacking two brain cells to rub together. I then started to jokingly call her a slag as per usual, then the wondrous juxtaposition of a word struck me- sleek. Someone who is both a slag AND a neek. I rather like it.
That girl's such a sleek, did you hear about her and her lab partner?
