Two words came together, to make a whole new one. First word is something you wear, and the second is what your wear it on. It's meaning may be unoriginal, but at least its economically accessible.

I work in construction, I hold things together. You can bite me, but it's frowned upon. Also, I can bite you back. I have a bed, but I never sleep. Men strike me repeatedly in the head to bury me. If I bend, I'm gone. You'd better be careful... I have a gun.

A refreshing beverage for the three months between winter and summer

The sound of me is deafening, Especially in an empty room, I am the sound of secrets, And of eerie crypts and tombs

I shed my flame when the wood grows old, A tiny spark in the winter's cold. I do not breathe, yet I glow and fade, A quiet ghost in the ash I've made.
