Slang for the blood disease diabetes. Often misspelled as diabeetis. Although the base of many jokes, videos, and puns, etc., it is a serious condition. After many well-known Liberty Medical Commercials in which celebrity Wilford Brimley mispronounces diabetes. Now a comedy empire.

Diabeetus is not just Diabetes mispronounced. Diabetes if NOT a blood disease but rather an insulin problem. Insulin is used to regulate the sugar levels in your blood. Some don't produce any insulin, some produce to much.

Diabeetus is Diabetes with enlogating of the testicals that get longer with age.

dia-beetus, also known as "the beetis" is infact not a unique strain of marijuana, but rather the reference to Wilford Brimley's bumblefuck speech impediment, and inability to pronounce the word diabetes. After Wilford Brimley's day-view on liberty medical commercials, "the beetis" spread like an std in a bro-infested frat house over the continental United States. Dia-beetus quickly became a youtube sensation, providing such hits as "rock me diabeetus" and "the funky diabeetus". The Billy Mays of yesteryear, Wilford Brimley's walrus like mustache and comforting hand motions will forever live on in the commercial brakes of late night television, and more importantly in the hearts of the American people.
