A mispronouncing of the word diabetes made popular by former actor Wilford Brimley in a series of TV commercials for the diabetes testing supply company Liberty Medical. Further made popular by the youtube video "Wilford Brimley-the beetis" where various clips taken from all the Liberty Medical commercials are mixed and put to a beat.
"If you have diabeetis, think again"-Wilford Brimley

fellatio (derived from Wilford Brimley's appearance in the movie Cocoon, where he got blown in the shower combined with his mispronounciation of the word "diabetes" in the Liberty medical commercials)
That girl gave me diabeetis last night.
