An incurable ailment which has plagued humanity for the past 48,000 years, it is 101% fatal and only recent advancements in the field of Roomba technology have been proven to cure it (for $34.33 dollars on Temu).

In reality Mao Disease is a fictional disease found on an ad for a Roomba-like robot vacuum on the online marketplace Temu, it was brought to light by Swedish Twich streamer Vargskelethor Joel on his first stream of "Temu Trash," a segment where he explores Temu and other cheap online marketplaces for bootleg and low quality merchandise. The page for the product featured music sung by a squirrel, and had features such as "Triad Sweeping," and the ability to return home when it's battery is low. Mao disease has since become a joke among members of Vargskelethor's Twitch chat.
I can't believe my favorite streamer and king of Sweden Joey Vargskelethor succumbed to Mao disease at the tender age of 30, we'll get you yet, Mao disease!

1. n. Vile, evil ruler of China from the end of WWII to the early 1970's. Killed millions of his own people with forced collectivization of agriculture, the "Great Leap Forward," and most of all with the power-restoration maneuver resulting from the famine created by Great Leap Forward known as the "Cultural Revolution." Faclitated a transfer of power to a group of even more evil people called the Gang of Four that included his wife. The tyrant can be considered on equal footing with the next definition.

2. n. The excrement of Microtus pennsylvanicus. You guessed it, its "mousie dung."
An example of Mao Zedong's thinking can be taken from his book, "The Wit and Wisdom of Chairman Mao," where he writes, "Politics comes out of the barrel of a gun."

A common typing error you make when typing "google maps" on mobile. When entering this, the top of the search results will display "Showing results for google maps, Search instead for google maos". If you actually google "mao", the result will be Mao Zedong, the founding father of the People's Republic of China.
Steve: "I accidentally typed google maos instead of google maps."
Willie: "Its ok, it happens on mobile all the time."
