kb
This is an acronym for "Okay, bye." There are many different contexts in which this would make sense

1. In place of goodbye, see you later, etc.
2. When a conversation topic has been exhausted and it is time for a new topic to be introduced, saying "kb" indicates that you both agree to start talking about something new
3. When you are talking about something that you suddenly realize you do not want to discuss, saying "kb" would mean that you no longer want the person to interrogate you about said topic
1. Yo Chelsea, I'm going to go to bed, kb.
2. *awkward silence*
Person 1: kb new topic
3. Person 1: So I was making out with this guy named Kyle, and he was awesome.
Person 2: Kyle, as in... my cousin?
Person 1: Kb. So what did you say was happening in Africa again?
