Junkolimic

The bulimic counterpart to the well-known junkorexic.

Junkolimics binge on unhealthy junk food that is then purged - either through exercise or vomiting. Junkolimic logic follows along the lines of, "if I'm gonna get rid of it later, I might as well eat something yummy.".

"What's up with Liam? He's always eating Taco Bell and shit, but he's skinny as fuck."
"That guy is a total junkolimic."
