someone who sends instant messages to everyone--including ppl they don't know. im sluts are also known to im someone the second they log on the internet. an im slut is also occasionally a profile whore, but not always.
Kaleb has only been on aim for 30 seconds and Kristen has already sent him an instant message. That is because she is an im slut.
