Howzabout we just play the game, and let the word develop on its own? If you want your word to spread, start actually using it. If it's a good word, it'll catch on. If not, it won't.
It works on two levels. One the one hand, you can be smacked by a toilet, hence the "bowl". On the other hand, it's like bowling, only instead of a bowling ball you have a large object which may or may not be a bowling ball, and instead of pins you have people.
Maybe "smacked"?
I'll go with either. Depends whether or not it was a toilet.
