An
ass-crack that gets exposed while BMX-ing vigorously. Gravity and
fast peddling causing pants to
edge down creating a "Crandall"
"Man, you'd better
stop peddling so fast, you are getting a Crandall."
"
Dude! I can see your Crandall from the ramp and it is gnarly!"
"
Hey, pull your pants up! I don't want to look at your hairy Crandall!"
