The state or quality of being awesome. Used commonly by awesome people to describe their natural awesomeness. Can be used as either an adjective or a noun. The word gah may not be used in conjunction with other adjectives as it takes away from the natural awesomeness of the word. It may also not be used by people lacking the quality of being gah. It has been established that if you question what gah is do not question what gah is, you lose any possible gah you may or may not have had permanently.
"Hey Teno, your like... GAH! today :)"

"Hey Teno, what is gah?"
