look up any word, like wcw:
 
1.
Jeina's are cute, warm, and quite bootylicious. They have a way of warming you to the core with a smile or a laugh. They love to talk and have lots of cool shit to say, but it's important to try and stop a Jeina at some point because they WILL go on forever.

adjective form: Jeinistic.
I'm going to the bar to find me a Jeina tonight, brah!

Damn girl I have never met a girl as Jeinistic as you are.
