The slight moaning sound a man makes while receiving a hummer.
There's no more musical sound than that of a hummer accompanied by a hummeroo.

A screecheroo that is flattened. I don't know what it does, but I'm under the impression that it hums rather than screeches.
My friend makes hummeroos every Halloween.
