Twitter Crash 

When a famous or influential person tweets a link to a website, causing the site to crash because of the massive flow of internet traffic that insues.

Usually this will only happen to websites that don't recieve a substantial amount of traffic, since their servers aren't ready for hundreds upon thousands of visitors coming to their site.

Why can't I click on this link that this actor just sent out? I guess we must have Twitter crashed the site.

I didn't even know I could Twitter crash my own website! I guess I have a lot of followers!

crash Twitter

(v) to do something really awesome or noteworthy. References the fact that anything really big happens (season premiers of TV shows, celebrity deaths, political action), Twitter crashes. Can be used sarcastically.

The same-day death of Michael Jackson and Farrah Fawcett managed to crash Twitter all damn day.

(sarcastically) Well, Dave, you're good in bed, but it's not like you're gonna crash Twitter or anything.
