Slang for mid to high grade cannabis flowers intended for smoking. Quarantine never refers to kif, hash, vegetable cannabis matter (I.E. leaves, stems, seeds,), or any form of cannabis intended to be ingested such as but not limited to hash brownies or cannabutter.
Quarantining is driving (slowly) in a car by somebody's house and screaming "Quarantine" as loud as possible and laying on the horn. This activity is usually done late at night (but could also be done in the day time) with a group of people that is used to disturb big parties, or used as a prank to someone.
Elizabeth wasn't too happy about her house party getting Quarantined. It caused major disturbance and no one knew what was happening.
