The crashdown

A crash course in something.

Man, I didn't understand anything until Brandon gave me the crashdown.

Crashdown Cafe

A fictionous place in the WB's "Roswell" TV series. Nancy and Jeff Parker and their daughter Liz Parker own it. Maria DeLuca, Liz's best-friend also works there. Is usually the place where the teenage aliens and the human girlfriends/boyfriends hang out.

You: "Wow, the uniforms Liz & Maria wear are so... funny!"
Me: "Well, it's "Roswell" and since the 1947 crash, they have the whole hoopla with aliens are included in the Crashdown Cafe."
