moonbait

1) An attractive girl's butt;
2) Picture of an attractrive girl showing her ass, either nude or partially nude, as opposed to boob bait;
3) Example of jailbait that is especially attractive because of her well-formed behind.

Look at that lil' ass! She's definitely some good moonbait! I wonder, though, what her boobies look like.

moonbrained

A state of being unable to remember seemingly simple things such as keeping appointments and returning phone calls.

While occasionally a natural condition for some people, it is most often a temporary state triggered by excess stress and/or a lack of sleep. It should not be considered an accurate indicator of a person's intelligence.

I didn't mean to stand you up at the coffee shop last night. I got a bit moonbrained and completely forgot we had plans.
