Tripping and hacky sack are a crazy combination. Sometimes I love it, sometime it just seems so wacky that I can't even wrap my head around the concept of kickin something around. A few months ago, me and my two friends tried dob for the first time. We kicked the footbag around for a while waitin for it to kick in, and then we just never stopped playin....ever. We tried to stop. Went over to a buddys and tried just chillin. Lasted like 10 min and then we were right back outside gettin our hack on. It's like it kept us safe from our brains poppin out and chewin our faces off. My legs were so sore the next day.
