Carolina Chuggington
The act of blowing smoke/vape into your sexual conquests anus or vagina, and then thrusting your phallus inside of them, and at every stroke as the smoke pushes past your dick, you make train sounds. This can also be done in a typical “train” or gangbang setting as well; you may share smoke.
Me and the homies gave that ol Hoe the classic Carolina Chuggington. It was lit!
