Another term for trunk or treat, the emerging American practice of children's trick or treating for candy out of car trunks whose owners have convened in church or shopping-center parking lots for the occasion. The practice, which is similar to sports-events tailgating of meals near a stadium, is meant to offer children a safer experience than walking the streets.
"I need to buy lots of candy. Time for Halloween tailgating."

"You need so much candy for a football game?"

"No, it's for trick-or-treating out of car trunks near the church on Halloween afternoon, also called trunk or treat."

"Very clever, these Americans."
