Overly excited about a simple thing; excited about something that most people would not find exciting.

A term used to reference cannabis/marijuana/weed.

When someone is so high on marijuana that they can't stop laughing.

When you're so fucked up that time itself has no meaning at all. Looking for the right candybar at Walgreens can take hours when you're geeking. You can spend a day trying to fold some origami model, or solve a math problem, or read a single paragraph.
Also related to tweaking.
When tweaking AND geeking, this time contraction is combined with a feverish hurry and awareness of your own "meth stench," not to mention a belief that what you are doing is of the utmost importance, and is not to be disturbed by anyone.

1. acting stupid.
2. how someone acts if intoxicated off a drink or a drug.

Geek can be used in 2 different ways.

2- Geeking = When a person is really fucked up on any kind of drug.
