Stands for "Prolonged Rocket Boost", which is a very advanced racing technique used in the game Mario Kart DS for the Nintendo DS that allows the driver to go off-road while still maintaining maximum speed.

There are two ways to achieve PRB:
1. Get a perfect start boost and snake perfectly (good enough so that your kart is constantly at full maximum speed). Continue to snake perfectly onto the off-road section you wish to cut across.

2. Snake perfectly after leaving a rainbow zipper without ever slowing down.

Any loss in speed whatsoever or use of a mushroom will end the PRB. The Karts best built for PRB are the Dry Bomber and Egg1, however it is possible with many more, such as the Standard DS, Standard YS, ROB-BLS, Poltergust 4000, and even more if you've got ultra skills in the game.

An exclamation made when your friends or family are teasing you to a point where you can't handle it anymore and a hissy fit is in order.

Derived from a YouTube user's famed outburst following Britney's lackluster performance at the 2007 VMA's.

Its called Pee Right Back!

Pre-rolled blunt

PRB is short for Pappy Road Block. This is a management employee who hinders progress within an organization. This individual would also abuse all privileges blatantly in front of direct report employees without remorse and eat skittles like a farm animal.

Means 'pee right back' taken from the shorthand brb where the first b is replaced with a p.
