Rapper?

Rapper is such a boring term! Other types of artists are showered with credit and unique names (rock star, queen of ___, pop star, celebrity, indie goddess, singer gone actress, model gone singer), but when it comes to those lyrical geniuses, what else can they be called?

Let's brainstorm, shall we?
-Swag machine
-Thug monster
-Gangsta man
-Beat bringer

...well, I planned for the list to be much more expansive, but I've suddenly run out of inspiration...
perhaps we should stick with rapper or swag machine, I believe those are best suited.
