Kids say the most nonsensical things

There is a student in my tenth grade class who speaks a different language. He knows how to speak English, but in the interests of keeping up his street rep he chooses to speak in some kind of bizarre slang I've never before heard.

For example, to "murk" is to kill. "Getting swole up" means to put on weight and get buff. These are new to me. So like the suburban white child of two suburban white people that I am, I have started a list of interesting things this boy says next to their definitions. Every time he says something I don't understand I ask him to define it, then add it to my list. The whole class loves this and he is proud of his unique contribution to my creative endeavors.

I figure I have a choice: pretend to understand and seem cool and probably fail, or admit to my extreme white suburbanness and treat it like a foreign language that I find fascinating.

One day I'll be in dire need of a really interesting character, and there he will be, a whole list of slang terms I can use to make him feel as real as the real kid he's based on.
