Mong

A Mong is used for all pronouns when you refer to them as dumb/oblivious and often do not get obvious hints.

This Mong won’t leave me alone. I’ve cancelled on him 5 times why won’t he get the hint?

Or

The Mong Hypothesis

Named after famous degenerate sports bettor Dr. Stu Mongworth Reagan, this is when a sports bettor takes the complete opposite of what Dr Stu bets on because he’s so dumb.

Dr Stu loves the Eagles -13.5 today. According to the Mong Hypothesis, we should put our life savings on Jets +13.5!!
