When a person does absolutely nothing but look at definitions on Urban Dictionary. There is no cure for Urban Dictionary Fever; the infected suffer until they pass out from dehydration or exhaustion. (They also tend to soil themselves because they don’t get up to go to the bathroom.)

Matt: I think he has Urban Dictionary Fever.

Mike: Sick dude.
