"Jesus Christ" Strap. Handle found in most automobiles above the door windows and employed when the driver opts for some crazy cornering or drives over a cliff. So named as passengers will often scream "JESUS CHRIST" when this phenomenon occurrs.
As Frank took the bend at 90 I grabbed the JC strap and hung on for dear life.

The handle in a car on the passenger's side on the ceiling above the door. It's called the JC Strap because that's what you yell when you have to use it.
"Yeah, just turn up here at the...JESUS CHRIST!!! *Grabs JC Strap*"
