ur

1) Prefix meaning earliest, first, original, prototypical. From the biblical city of Ur, whence came Abraham.

ENIAC was groundbraking, but Babbage's analytic engine is still the ur-computer.

2) The lazy Internet freak's way of writing the word you're. This word is as annoying as its brothers thx and plz. This word is most commonly used by teenage girls who think it looks cutesy and cool. (See hawt and seckzi.)

ur liek so hawt and seckzi, omg! LOL!
