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?

KB is usually a girl. She's very strong, independent, and and a natural leader. She's extremely smart and creative. Usually loves to paint or draw. She is a loyal friend and when you find a KB, don't loose her!! She's very special and you won't find anyone like her. You don't want to get on her bad side, because when you do she will destroy your social life. She's very popular so she has the power to do that. If you're on her good side though, she will give you a social statice and be you're partner in crime. KB's are rare, so when you find them, keep them!

Kind Bud. Good weed, light to medium green, crystals, red or orange hairs, well cured. No seeds. Usually has a very piney-skunky smell. Most often Northern Lights or a NL hybrid. Not to be confused with "Da Kine" which is a Hawaiian Pidgin term that can mean anything. This term is mostly used in suburban Maryland and DC. I haven't heard it used anywhere else, except NOVA. Sells for 35-75 per eighth. Maybe I'm getting old but every I hear the term "Headies" it makes me cringe.
Hey man what's shakin. I got some KB tonight come thru and check it out.
