kickdown some floorspace
phrase used by wooks and dirt surfersasking to sleep for free on your hotel room floor. Be warned! this type of dirt surfer is VERY hard to get rid of! They have no money any will beg you to "kickdown floorspace" until you give them a final answer.
"This dude "freebird" asked us if he can kickdown some floorspace before our flight to Phish in Vegas was even off the ground!"
