chronic boom 

The act of attaching copious amounts of marijuana to any type of dynamite or firework which results in a massive explosion of kush that spreads a god-like odor throughout the land.

Last night, I got some of my best afghan kush and tried a chronic boom. It was an amazing sight.

Chronic Boom 

An extreme high by marijuana. Or a large pipe or smoking utensil to inhale marijuana. Or any exageration used to explain marijuana.

Preston has a sick piece. Its a chronic Boom.

Last night was a Chronic boom!!!
