A condition a person (usually a girl) has when they have an extremely beautiful amazing redonkculous piece of A$$ that no other word can describe other than donkitis.
Breh! Did you see Karley today?! She for sure is suffering from that donkitis! What's that you don't know what donkitis is? Ya know Kim Kardashian and Nicki Minaj... yeah well they both got that donkitis!
