Jenny Lewis of Rilo Kiley, Ben Gibbard of Death Cab for Cutie, and Jimmy Tamborello of dntel created the synthpop group The Postal Service.

When you post something to a social site e.g. facebook, twitter; and you regret it after a few seconds or minutes, but are too lazy to remove it. Or you just want to know the response that it will get, but eventually regret ever doing so.

Over-reaction to a perceived minor breach of etiquette.

Basicly, "going postal" is pulling a uzi, assault rifle or most any other firearm out from under your jacket and going nuts. That is, wasting anyone and anything you see, and then probably yourself. A bit like going apeshit.

A slightly inde band created by some members from DCFC (Death Cab for Cutie). Most notably known from thier work being featured in Garden State. Quite "film schooly" as a personal opinion, and certainly something different to listen to. Great to depart from the mainstream "music" that is fed to us through basic-cable "music channels".

to succumb to fatigue and tension, to be become violently angry(from a series of incidents from the mid 80s to the 90s where various postal workers went on shooting rampages)

While on vacation at the beach, a random hookup which consist of at least a blowjob.
