Ubergammin is a rare radiation sickness caused by jacking off while standing in gamma rays. The main noticeable effect is your dick shrinking to the size of an Asian's. Some side effects are becoming an Albanian, which develops into having an Albanian accent.
Guy: Girl, look at my dick! *pulls down pants*
Girl: *chuckles* It's the size of an Asian's!
Guy: Shut the fuck up! (said in Albanian accent)
Girl: Were you jacking off in gamma rays?
Guy: Yes (also said in Albanian accent)
Girl: You must have Ubergammin!
