What you say when someone accuses you of Facebook stalking. Since it just showed up on your news feed, you couldn't have been secretly reading their profile, right?
Joe: Man, that party last night was sick...

Mike: Oh, that one you went to at 9:23 pm at Bob's house?

Joe: Whoa, how did you know that? You aren't stalking me, are you?

Mike: ...it showed up on my news feed.

To show someone up can be used in:

"You talked the talk but he walked the walk, he totally showed you up."

"I can't believe I got showed up by a little girl!"

This phenomenon describes how some people react to undesirable and uninspiring work situations. This phenomenon is mainly applicable to people working boring, mindless jobs, most of whom perform rote work -- e.g., data entry -- or are paid simply simply for their presence -- e.g., a booth attendant. Activities that constitute 'shutting down' and checking out' include: napping, reading, sending excessive/unnecessary text messages, and listening to one's iPod.
Elliott: I'm surprised Tom hasn't gotten more sleep today -- doesn't he have to work the graveyard shift tonight?
Mark: Yeah, but remember, he's a booth attendant in the middle of the night...he's just going to Show up, Shut down, Clock in and Check out.
