When you and your friends have just smoked a delious bowl and your glass piece is clogged with weed, making it impossible to take a monster rip and someone decides to make a stand and unclog the piece. They do so by sucking in as violently as possible sucking in any buds that may be clogging your inhaling mechanism. He then makes a face of disgust and opens his mouth and shows his tongue. His tongue is covered in ash. He has sacraficed himself in order for the smoking session to run faster and more effiecent.
-"Dude, whats going on, I barely got anything off that hit"
-"I was afraid of this."
-"Afraid of what?"
_"I must 'Take one for the team'"
-"You brave little soldier"
The term 'krunk' is derived from the word "crank" referring to the crank on an engine, key in the car igition, etc. To get "krunked up" is to get "cranked up" or to get going/turn on. Thus, derives the association between alcohol and drug use.
"'Na sun, goin out der n krunk up dat ride!" means
"Now son, could you please go outside and start the automobile for me?"
