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

The first syllable is "high" and the second is "purr", therefore to be hyper is to be like a drugged cat. Yes. Really.
"This definition of hyper on urban dictionary is completely incorrect."

In the furry fandom (and most likely other places with sexual minorities), hyper means to be excessively endowed to the point of ridiculous and unrealistic proportions. This can also be combined or replaced with the muscle fetish to mean unrealistically gigantic muscular proportions.
Furry #1: "Hey did you see the artist who drew that hyper mouse?"
Furry #2 "The one with those really really huge boobs, right?"

Or

Furry #1: "Man, I wish I was hyper muscled..."
Furry #2: "Why? You wouldn't even be able to move with all that beef on you."
Furry #1: "It's just for looks."
