[citation][nom]TemjinGold[/nom]Err... what's "Hump Day"? Is that like a national holiday promoting sex?[/citation]
I'm going to assume you seriously don't know and tell you that Hump Day is a euphemism for Wednesday, which is at the middle of the work week. For most working people, Monday is like starting at the bottom of the hill, you work and work until Wednesday to get to the top of the hill, and then you're "over the hump", so to speak, for the rest of the week, which you sort of just coast through because you're excited that the weekend is close.
Aren't idioms such fun? /sarcasm
On a somewhat unrelated note, Jane's vocabulary makes me laugh and I think I will start using British terms for everything just to confuse people.
