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.

The unofficial spelling for diabetes that was created due to popular media and meme-makers. Used improperly in text messages due to being plainly humorous to most young people. However, it is not necessarily a nice word to use in public in offense to those who have suffered the diabetes condition(s). It was originated from a meme made after a public message from Wilford Brimley.
Diabeetus is caused by having a glucose "high," when a person cannot either process sugars naturally or had to much over a span of time being obese.

Type 1 diabeetus is a chronic condition when the pancreas can't provide enough insulin to counteract the glucose.
Type 2 diabeetus is a chronic condition when the entire body fails to process sugars.
Type Infinity diabeetus is when one man consumes all of the glucose made in the entire universe and when all matter is processed into sugar that it consumes, so that only it exists and lives yet perishes after the consumption of all of the glucose to exist. This is the most bittersweet way to die eating what you like.

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.
