You can be sitting around on a Saturday afternoon and suddenly think "Oh I want some crisps. And maybe some toast..." Its often really a randomfood craving. Suddenly you have the urge to eat icecream. There is none? Well eat something else in the fridge.
A lot of the time its the effect of weed greenie pot or whatever you want to call it. The proper word is marawana. That was spelt how its said coz I got no clue how to spell it!
A WARNING: If you have munchies at someone elses house, DO NOT EAT THEIR PRINGLES OR JAFFA CAKES! The only thing that allows you to eat their pringles or jaffa cakes is if they are eating them with you.
One thing - it doesnt alway mean you've had a green day if you've got the munchies! People randomly get them a lot. Dont accuse your lil sis/son/mate of being a stoner coz they ate everything in the fridge, smell them first, or whatever.
I got the munchies! *eats crisps, icecream, toast, apple and cakes*
"I am so pissed off right now! Tommy came to my house when he was stoned, and he had the munchies! THERE ARE NO PRINGLES OR JAFFA CAKES LEFT! I'm gonna kill him! He didn't even leave me any greenie either..."
the day after eating weed when you have extreme urges to poop. similar to diarreah...you stomach will start by turning over in itself and then it will come just wait
