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.
When you are jerking someone off with one hand while using three fingers from your other hand to spin one testicle and sucking on the other testicle. Milking the testicles like one milks a cow.
"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.
JC Slapper refers to the Welsh Light Heavyweight boxer, Joe Calzaghe.
JC refers to Joe Calzaghe's initials while Slapper describes his style of fighting. Instead of throwing punches like a man with a closed fist he "slaps" while apparentlyeffective, it still makes him a pussy.
JC Slapper, while holding a record of 46-0, his record is highly padded and very protected.
