Gresser 

pronounced "gress-air", to gresser someone means to briskly walk toward a destination, without giving the slightest fuck about anyone or anything else. A true gresser will not wait for you. He (or she) gives zero shits about whether you are standing next to him or not. Sometimes hilarious, sometimes annoying as shit.

Person 1: Hey wait up!
Person 2: **walks away
Person 1: Wow... what a fucking gresser
