A short term feeling of having lots of energy, one who is hyper usually does crazy/stupid things and laughs a lot. Often called a "natural high" and is caused by mutliple things: friends, sugar, lack of sleep, night, etc
I was so hyper last night i couldn't stop laughing.

In general, the word "hyper" means...
Over; Above; Beyond; Excessive
The basic meaning of "hyper" is "beyond" or "above", so it's obvious to use "hyper-X" for the higher-intensity of "X". As we say... Hyperactive man
