Parent Over Keyboard. Used as a alternative to "POS" when a parent is watching you talk over IMs. Used as an alternative in conversations because "POS" is also an abbreviation for "pice of shit", and may be confusing in normal conversations.

Get the pok kai mug.
a cantonese slang, to die. Literal meaning is to fall down out on the street and die. "pook" is the sound of the head hitting the pavement. "Gai" is the street.

It is used when someone is angry at someone or something and wishes the person dead. Or just used when one is angry.

(i am adding this because none of the other postings had the literal translation of the term)
Damn...that pok guy just ran a red light and almost hit me!

I hope that asshole hurry up and pok guy!

I've been working so hard...I'm gonna pok guy.
