|1.||AIM Instant Messenger|
Messaging system created so that low lifes can chat online with the "friends" that don't like them enough to either answer their text messages, or actually talk to them in person.
situations such as these bring great relief to the "block" button.
susie: i wonder why that hott guy hasn't answered my constant text messages for the last three and a half hours
-after logging in to AIM Instant Messenger-
susie: oh, no worries! he's online!
