The liquid some men seek from a woman's cunt. Just as a person may only eat a cream egg for the cream in the centre, some men chose to eat out a girl purely for the 'Flem'. Flem is the natural lubrication produced inside a cunt before and during sex.
Husband: "I am so fucking hungry get me something to eat".

Wife: *Opens her legs revealing some flem*
Husband: *Enjoys the Buffet*

An insult, meaning the same as tight,deep,out of order. Could also be used instead of fuck.

There is no literal translation, but it basically means anything rude.

An amazing word to describe that catagory of people whose personality lingers between their gender and the next. It's a word to use when people have grown out of the words such as "tomboy" and "tomgirl".
"I don't get it, she acts so much like a man sometimes."
"Yeah, don't worry, she's just a flem."
