If Teeth Grew Like Nails, You'd have to cut them

Bite your tongue, ignore the splinter
Seen it in a nightmare
Seen it in your heart
Shiftless and unsure
Spit more splutter than the saliva in your mouth
The blackest bile
Throwing up sharp gooey smiles
You've turned into something
That puts the weakness in my hands
But you hear what you want
When I can't even talk
Throwing stones at walls I'll never climb
You make hell this place on earth
