geek out is a lame term used to describe when a person starts to get really fucked up and cannot control their actions, words, or emotions. Usually used in the mid 90's or in a hippie society.
I told you not to let that motherfucker hit the bong again, see he's starting to geek out and shit.
Hey bitch, if you start to geek out I'm going to slap you right in your face!
One that has extensive knowledge in all areas and is able to explain himself quit well about information in the world that is important. Geeks actually have a college degree because you can’t spell geek without EE. While a nerd is one that continues on at the community college trying to work at “Game Stop” because they think its cool that they can live at home and play magic any time they want. Nerds know enough to talk to other nerds on a few small topics.
