I know a guy

When you know how to personally contact an expert in a particular field--especially when the subject is unusual, strangely specific, or illegal. Often used when you do not want to reveal the identity of the contact or how you came to make the acquaintance of such a person.

Co-worker: "The boss said a hooker took off with the USB flash drive with all our vital code stuck up her vagina. How are we going to find her and get it back?"

You (not wanting to talk about how you did IT for a pimp/gynecologist who owes you a favor): "I know a guy."

ya done know

Of Jamaican origin. The literal translation to the standard North American English dialect would be "you already know" or, "you know it!". Used (to the writers knowledge) mainly in Toronto, Canada (in its North American variation) where it has found use among the wider (mostly younger) population and, of course, in its original Jamaican patois dialect everywhere Jamaicans are found (that's globally!).

Used to:

a) Emphasize the validity of a fact (usually stated immediately after the phrase) - e.g. "You done know they're running a scam."

b) Respond affirmatively to a query - e.g. Q: "Are you good for this money I'm lending you?" A: "You done know"

c) Express one's assent or agreement - e.g. A: "Boy, it's hot out today!", B: "You done know"


The phrase is also varied to fit the context of the conversation by changing the pronoun used (i.e. "She done know", "They done know", "I done know", etc.)

Jamaican dialect example:
"Yuh done know di gyal a lie 'bout 'ar panty size. Everybody know seh 'ar batty bigga dan dat!" (insert laugh here)

Never Knows Best

A philosophical statement written on Mamimi's cigarette in the show, Fooly Cooly (FLCL). Some viewers believe that the full message is in fact, "Tasuku Never Knows Best," but it is disputed. The significance of the quote is relative to the individual.
