rollfucking 

similar to the practice of boobfucking, this term refers to the sexual act between a man and woman such that the man takes his obese partner's fat rolls and wraps it around his wang and resumes to "fuck it" in them same manner until sexual culmination.

Hieu: Do you see that morbidly obese thing over there that resembles a female? I want to hook up with her and start rollfucking those flabs!
