"The Rush" is when people are under-the-influence and driving with their friends. This usually occurs on a precipitation filled night. What happens is, the driver of the car is speeding because they are fucked up, and the car begins to spiral out of control. The only way it is considered a rush is if the driver skills it and everybody lives.
Police, from the orginization in the early days of the american alaskan territory. The orginazation that became the coast guard was called the rush. People who tried to catch to many seal would have to leave before "the rush" showed up.
the apparent 'high' that a certain obviously goody two-shoes feels (initials of D.K.) when ever he does something remotily sneaky, which is in no way bad at all, but he thinks so anyway. basically its the 'thrill' experienced by un-bad kids who do something like steal a pencil or backdoor their buddy and not have the common courtesy to give them a reach around (long live full metal jacket)
shit, K just snuck into the PACC, hes high on the rush!
