I'm gonna give away a secret: sometimes I look to online rhyming dictionaries for ideas. This is ridiculous because I don't really write "form poetry", but how could you not love this (see below)?
Dude, "blood cup"? This stuff writes itself. "Fairy cup," "charred pancake cup". The resources of the world amaze me to no end. And your challenge, sweet reader, is to write something using either "charred pancake cup" or "moustache cup," and then send it to me so I can laud your genius.
