Term made famous back in the 1970's when many gay men flocked to truck stops and highway rest areas to get their daily fill of man gravy. Trucker's Smucker's is jiz left on the cheek or chin after a hastily performed blow job has taken place.
"Hey Trevor, you might want to hit the can and wash your face - looks like you have some Trucker's Smucker's by your left dimple."
