Kb is an acronym for "kind bud". It is a nickname for very potent strains of marijuana. It generally has a thc content that's 21 percent by weight and has long red hair growth, a sort of frosted appearance due to the high thc content, a light green color (though this can vary with every strand). Kb is usually a denser and rounder-looking bud and is more difficult to break up.
Examples in speech:
"I'm about to roll a fat blunt with 2g of kb"

"I need about an 8 of some kb"

"Hit me up when you get that kb."
