Yardsailing is the act of driving around town searching for yard sales.

Yardsailing is usually done by people who buy random things for a cheap price and sell on eBay for way more than what it's worth.

Yardsailing is also practiced by people who enjoy going to yard sales for the fun of it.

A person who goes yardsailing is known as a yardsailor. Yardsailors typically wake up early, search newspaper adds, and stay out till every last yard sale has been sailed.

Yardsailors are not to be confused with passerby's who stop at a yard sale just to have a look.
"Check out that yardsailor! Man, his car is filled to the top with old yard sale junk!"

"WAKE UP! WE'RE GOING YARDSAILING!"

"Who knew this crappy chair I got for 2 bucks would sell for 40 dollars on eBay! I'm glad I went yardsailing!"

The act or art of biffing it while doing any kind of thrillsport. IE, motocross, snowboarding, wakeboarding, rock climbing. Etc. In most cases, the wreck is so significant, that a string of gear is slung in and or around the impact area simulating what is typically know as a (Yard Sale). However taking into consideration, that one is typically (sailing) prior to this now recognized art of the dynamic crash, the word YardSail was born.... Note- not to be confused with a Yard Sale.
Damn bro, it appears as though we have a slew of squids and rookies out here today. SURELY we will see some massive YardSails throughout the day.
