When someone eats or drinks non-stop junk food for a long period of time, we call it a "junkathon"
Example One: "John's cat died today, hes on a Junkathon."

Example Two: "Sammie's preganant, and yesterday she had an insane junkathon. She had three Ice Cream Cones and went to McDonnalds four times!"
