The action of unblocking someone and blocking them again on AIM in order to see if they're online. This is about the equivalent of knocking on someone's door to see if they're home, then your nerves collapse and you run the fuck away before they see you. Usually occurs after a terrible conversation, which ends up with one person blocking the other. Of course, this just makes the person they blocked attractive, so they make frequent spot checks to see if you're online.

It's the malady that sets in when the user realizes "services" like Foursquare are a complete and utter waste of time.
Hey, I just became Mayor of my workplace! When do I get my pay rise?
Heh - that's only because Mary stopped checking-in on Foursquare. She has total check-in fatigue.

Sometimes, females get out of line in their dealings with you (cursing at you, cheatin on you, spendin your money, etc). When this happens you gotta check that bitch, which means either verbally or physically letting her know who the man is in the situation. Failure to check a bitch leads to a man becoming a simp who women don't respect. All macks know that checkin a bitch is a crucial part of the game.
)How to check a bitch and how not to check a bitch)
Simp: Please honey stop the yelling I'm sure we can figure this out.
Mack: Bitch you need to shut the fuck up. I don't know who you think you are but the man is talking right now and you don't ever speak to me like that ya hear?
