A rare condition where one must inhale memes. Memes such as "21" and "doge" are the best for the unlucky people with this condition. The best inhalation method is by screaming memes into a barrel, bottle or anything that can be sealed and breathing them through a straw. Other symptoms are, Vietnam flashbacks, Harambe images appearing all over the body and only being to read Comic Sans.
A disease that causes memory loss, pepes to appear on the skin and finally the skin turns pink and you will being to have random seizures on the ground.
When some one is up to date in all of the dankest and popular memes of 2019 (big chungus). A person who develops memeitis is most likely one of 3 things 1. A dead memer:this type of memer has contracted the most lethal form/type of memeitis they will hit the dab like wiz kalifa and whip/nae nae at unacceptable levels at random times 2. A dank memer is when a person contracts the most drug/marijuana filled memes such as the song smoke weed by snoop dog and 360 no scopes
and finally 3. The Pure memer is when a person is diagnosed with the rarest case of memeitis it has no flaws or weed (sometimes) just the pures and best up-to-date memes of our centurie.
Josh ah all that retard talks about are snoop dog weed or 360 no scopes I guess that means he has memeitis in the dankest of forms
