look up any word, like sapiosexual:
A zen like state of existence. Contentment bordering on subtle excitement. Truly living in the moment or having a transcendent moment Also, similar to "stoke" or "being stoked."
The origin of this word stems from Louis Armstrong who not only played jazz (peaceful, zen-like), he also sang "What a Wonderful World" displaying perfect Louisness in his attitude toward humanity.

Someone who is absolutely everyones friend. Literally, not one person in his town does not know his name.
Very kind to everyone he sees. He is also great with words, as he writes music. So he's musical, and usually very loud when he plays drums!
However, he is romantic; in every way possible. I can't keep my eyes off his. Nor my lips...
He has a hard time finding love, probably because he is very spontaneous with his actions. He often meets girls, then loses them to other guys. But somehow, he won my heart...
I still can't believe how I could get a guy as amazing as Louis...
