I thought this was gonna be about that movie with the chick that had teeth in her hoo-ha. But oh well haha, this was good. These were my favorite lines:
When I swallow molars is the only way our "crowns" clash,
Here's a brown bag for your sad frown - bounce, hag,
I like the way the second line sounds, with the inverse leading to the rhyme scheme. I think inverses sound the best when only two syllables, just my opinion. But yeah, good stuff.
