U.P.P stands for Uneducated Poo Poo which means someone who didn't have a education by someone with knowledge and wisdom and was raised as a ignorant cave man basically from a trailer park and thus is feces or a piece of shit to society and the public and the majority of the population want to spit on U.P.P or throw there garbage from Mcdonalds in there direction. U.P.P tends to be impulsive, egotistical, lieing, violent, sometimes overkill, prejudice, homocidal neuralizing, ignorant, sometimes Satanic, concealing, selfish, manipulative, vengeful, who speak in slang with no words coming out of there mouth that are from a dictionary longer than 5 words usually if you know what I mean. U.P.P are known to be so retarted and a joke that they send innocent children after a Life Review coming back as respectable with integrity to un-called for Hell in weird uncalled for negative based Universes or realities in micro size concealed in Simulation Virtual Reality Programs and not Real Dimension Real Life like commendable beings would who society makes monuments and honorable statues for

The most amazing last name. Ever. Confuses many, makes others questions.

We've heard all the jokes.
It would be hilarious if we married someone with the last name "Down," we've gotten over the list of possible first names that would suck, like the direction, U-P-P, and yes, it IS our real last name.
