This term refers to the part of one's bowel movement that has been transformed inside the guts from cheese into a harder-than-usual portion of doo-doo. One might be in the ecstatic throes of a smooth dookie session, only to have the brown train interrupted by a cheese plug. One antidote to the cheese plug is binge drinking.
Say man, why do you scarf handfuls of mozzarella every time we make pizza? Nahmean like, how you gonna deal with the cheese plug?

Not to worry, I'll be taking 30 dextromethorphan hydrobromide cough gels immediately after dinner. The resulting shits delivered by those things will blow out any cheese plug.
