UPDOG (Ultimate Paralyzation of Damaged Organ Genetics) is a process in the BOFA (Body Oscillation / Fatal Area) in which DNA is modified into having LIGMA symptoms in the genetics. This is only a stage 1 on the BOFA power level, however a person will suffer from intense addiction to Fortnite, get free Xbox Live or PlayStation Plus, and the ability to gain a free copy of the Save The World mode at birth. Though most of these symptoms sound positive, one negative symptoms will occur, a UPDOG victim will forever stay a virgin. It is unable to change that fact. Some popular examples of people with UPDOG include: TSM_Myth, every 12 year old, Ninja, Runescape players, and most likely you.
Person 1: Updog
Person 2: What’s Updog
Person 1: It’s when you get a free stuff from Epic for having special genes
Person 2: At least I’m not a virgin
