Used to describe a series of calamitous events that occur over a short period of time, that are either intrinsically linked, completely random, or fall somewhere in the middle.
Joey: Dude you won't believe what has just fuckin' happened to me over the last week!

Bret: What?

Joey: Well on Monday I got fuckin' burgled by pikey's. On Wednesday I wrote my car off. On Saturday my missus split with me cos I go no fuckin' money or car anymore. Then to top it off this morning I slipped up fell in some fuckin' douche!

Few can consume enough cannabis to become one. A colossal stoner is the grand archmagister of the stoner kind. A colossal stoner's tolerance break lasts about half an hour. The period between each joint when he/she is not smoking is just about as long as the time it takes to roll another joint. If a colossal stoner greens out, their immediate action upon waking up is a wake&bake. A colossal stoner on average will have enough cannabinoids in their system to get arrested and charged for trafficking.

A shitstorm of such epically huge proportions that it blocks out the sun and throws the world into a stinky, everlasting night. Metaphorically, of course.
My mom found my Perc 30's. She is sharpening a knife, and my dad is preparing to waterboard me. What a colossal shitstorm I have screwed myself into!
