Also, crunk. The PAST TENSE of crank, as in to "crank it up." If the volume or level of energy and intensity in a club, or a level of anything for that matter, like a high for instance, can't be "cranked up" any further, than it qualifies as crunk or krunk.
"Crank the volume? It's already crunk"
"We the type of people make the club get krunk!"
"I was blazin' rock 'til I got krunk!"
