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.
2. "Your father I will be at your aunt's this weekend. No freewheeling with my car."
Derives from tits being called wheels.
