The term used to name the action of "Reading and Not Replying" over Blackberry Messenger. It is considered to be the rudest infraction of all Blackberry Messenger etiquette.
When a message is sent and delivered from one device to the next, a "D" is present beside such message. When opened, the "D" turns to an "R". Both the sender and recipient are aware of the situation, and in some prestenses, it creates an awkward moment.
Yo I just sent Natalie a text over Blackberry Messenger. I hope she doesn't give me the RnR
