Get the Sleek mug.
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?

(Apologies, I spelt this wrong in the first submission)

Faux Sleek is where an object gives off the appearance of being capable of high quality performance, however this is just a visual appearance. The object's performance does not match it's design.
*A slender redesigned train arrives at the station in Brisbane

Person 1: Check out the shape of that train. I bet it moves super fast!
Person 2: Nah dude, that's faux sleek.

An individual who is particularly more important than others,
standing out from the herd because of said superb sleekness.
