A "cumby's run" is the journey one takes to reach this area of divine sactity. It could be through the woods, via the road, or through your own mind.
The proccess usually takes place when the sun has retreated. There are a set of rules to justify this:
1) A Cumby's Run must take place only after 10:00PM
2) A Cumby's Run must be done with one or more person
3) There are no more rules.
"dude, let's just go on a cumby's run and clear your head a little bit, ya know?"

"that have 1337 whoopie pies and like breakfast sandwhiches and like alot of poonaney avaliable for everyone!!!"
"yo d00d, you wanna go for a cumby's run now?"
"oh, yeah yeah definitely."
