Name That Punctuation!

Readers of Blog About Town tend to enjoy contests and typography, so I want to make sure that all of you are aware of a punctuation-naming event at Emdashes, which is itself named after punctuation.

The challenge is to come up with a name for the upside-down question mark familiar in Spanish.

So far I'm especially impressed by Carolita Johnson's quiggle, which sounds delightfully naughty to me. My own suggestion is interroflip, a spin on interrobang.

So I suppose the upside-down exclamation mark might be called a bangflip or a flipbang.
