KB really means Kind Bud it's used to describe sensimilla or seedless weed that should usually be soft, green, sticky, and contain orange or red hairs and or crystals. This term is used if the chronic you find is usually the same type of high grade weed. If you don't have any Purple Haze or Blueberry in the area and all you're used to is regular Chronic it's called 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?

Coined by firearms journalist Dean Speir, kB! is shorthand for "kaBOOM!"

Usage: Verb

A situation where a firearm has a catastrophic failure causing it to explode. The situation typically arises from a ruptured bullet casing, but may also be caused by a barrel obstruction, or a having too much powder in a cartridge.

While a kB! will probably render the firearm inoperable, and unsafe to use, the firearm should contain much of the explosion.
I had my glock KB on me yesterday! The gun's shot, but I'm ok.
