freewheeling 

(also "Freewheelin'"
1. Free of restraints or rules in organization, methods, or procedure. Heedless of consequences; carefree. Rambling, often aimlessly and without any kind of objective, either verbally, artistically or physically. Could have both positive and negative connotations.

2. Driving a family member, friend or acquaintance's car without permission. Technically auto theft, but the relationship to said car owner makes a legal charge highly unlikely. Often perpetrated by teenagers without a license or with only a permit.

1. "Man, Ryan Adams was freewheelin' tonight at his concert in the park. He must have been really drunk. But he was good enough so that I didn't ask for my money back."

2. "Your father I will be at your aunt's this weekend. No freewheeling with my car."

freewheeling 

To "coast" in a manual-transmission car without being in gear, i.e. with the clutch pedal depressed or with the shifter in neutral. Widely used on hills and such to save gas, since it keeps your revs at idle speed while still moving.
