Awesome New Word I Learned This Week

Locin' (verb). To go crazy or freak out on someone (I think).
As in:
"Damn, Miss W.! I was just askin' a question, why you locin'?"

Now, why can't I make up words? It's like, if I went around trying to say that, people would be like "who are you kidding?" But some people, they make up a word and for some reason it sounds like it was always a word.
It's not fair. It's bunk. It's wack.
I can't even pull off words that are already words.
