A rare strain of vaginal fungus, cases usually appearing in the MidWest.

The word evolved from the term vag fungus (abbr. vaginal fungus) and was eventually shortened by doctors in residency who wanted to break the news gently.

Colloquially used to refer to 'a load of crap.'
Doctor: Miss, what you have is a load of bajungus.

Patient: Doctor, that's silly.

Doctor: No. Really.

Betsy: Dinner's on the table, honey!

George: It smells like freaking bajungus!
