phrase used when someone is bragging to you about certain price they got on something.
origin: this phrase was seen sometime in 1993 on a hand written poster advertising a carpool from collge back to the Boston area. Actual phrase was "I'm cheaper than the bus". After finding out who wrote it, it became an inside joke (how much is this, cheaper than the bus haha) but quickly became a regional term for a good deal.
"glass pieces at Conventry were only 30 bucks!"
"wow, those are cheaper than the bus"
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!"
