I think I've offered this up before and nobody has taken the name yet that I'm aware of but based on the popularity of spongebob squarepants, I've always thought plungebob tiltpants would be a great name for a pinball arcade...of course, that might be because spongebob always seems to be on when my son is watching TV.
I think you're looking for a name for your company though, right? In that case, you're probably not going to be using the name at an actual physical location so you could use something like Xtra ball or ballin'. If Centerflank would allow it, "bonus sexy time" is always a thought
