A compression release engine brake, frequently called a Jake brake or Jacobs brake, is an engine braking mechanism installed on some diesel engines. When activated, it opens exhaust valves in the cylinders, releasing the compressed air trapped in the cylinders, and slowing the vehicle.
Although Jake brake properly refers to the Jacobs brand of engine brakes, the term has become a genericized trademark and is often used to refer to engine brakes or compression release engine brakes in general, especially on large vehicles or heavy equipment.
They are often not allowed in to be used in towns as they create loud, clattering noises.

I saw a semi get pulled over because he pulled his Jake Brake in city limits trying to slow the rig down in a slower speed zone.

Get the brake dust hoarder mug.When being tailgated, you tap your brakes frantically in morse code type fashion. You tap them hard enough for the lights to light up, but not to actually slow down. It'll confuse the tailgater and they will back off. If they continue to tailgate, continue to freak out on the brakes. A skilled driver will be able to brake freak with the left foot while still using the right foot to maintain speed.
The other day someone was tailgating me, so I did a brake freakout and they had no choice but to slow down.

Get the Brake freakout mug.When driving a car with a lady friend in the front seat, the act of applying the breaks suddenly so you can extend your arm to make sure they don't fall forward too much, and "accidentally" grab at their chest while trying to "protect" them from harm.
That light turned red out of no where! I had no choice to brake rape you, otherwise your head would have hot the dash! Mmmmm....boobies....
