Hot Dog Roundabout

When a person places their legs behind their head and inserts a whole package of hot dogs, (kosher or not), into their rectum, forcing them to come out of their mouth. The cycle is continued with the regurgitated hot dogs being re-inserted, hence the name "round-a-bout"

Dude, can you believe my mom is feeding us the same hotdogs she used for a hot dog roundabout ?
