Is "smashing" something that Brits say?
I've never really heard it used as an adjective here in the states except in the Orbit commercials (It's more or less Wrigley's, but their ad campaign seems like it's either made in Britain or it has that Pythonesque British sensibility).
If so, I could see some value undeveloped. If not (i.e. if it's just used to denote stuff hitting other stuff), maybe low $xx.
Poker names seem to do well parked/developed. Slap it up on Sedo and you should make some money.
