Dia-beetus
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.
Man, so fuckin' bummed, i heard kimbo slice may retire because he has dia-beetus, beetus, beetus, dia-dia beeetus.
