A Performance-Based Brake Test (PBBT) is any device which can quantitatively assess the braking performance of a vehicle. This is done through direct measurements of the brake forces at each wheel, axle or for the vehicle as a whole. Such devices include roller dynamometers, flat plate brake testers, breakaway torque brake testers and drawbar-type testers. Each of these devices can determine the brake forces without restriction to brake type (disk or drum) or energy supply (air, hydraulic or electric). In addition, PBBTs based on mechanical or electronic decelerometers can assess the overall vehicle braking capability through a stopping performance test in which deceleration and/or stopping distance is obtained, also independent of brake type or application method. Some PBBT types have been used worldwide for decades for both safety inspections and as part of regular Preventive Maintenance (PM) work in fleet shops.

Get the pbbt mug.An abbreviation for the English version of the Arabic honorific Muslims say after of the Prophet Mohammed (pbbt!). Shia Muslims also use pbbt! after the names of Shia imams. The exclamation point is a modern addition derived which does not occur in the original Arabic.

Get the pbbt mug.PBBV is a salmon-colored monke that normally "spawns" on the bridge in the Forest Map. It talks in a "deep, raspy voice". It normally says something along the lines of "PBBV is here. PBBV has become hostile".
There is also a video by chippdbanjo about PBBV named fileproof-appke that starts off totally normal but after probably 1 second the video's colors get more vibrant and then you'll start to hear a text-to-speech-like voice saying an IP address-like number combination and repeating them 2 times (it's shown below here you moron):

Get the PBBT mug.A word used for simulation of violence. Hitting in the fgace in particular. This noise is most effective when simulating hitting with a bat. A spludging sound can be added to simulate blood spatter.
