When you eat really good food and your mouth tingles
"Oh baby that taco gave me a mouthgasm"
The main theme of having Hypomaniacitis is being extremely insecure and trying to appeal to popular people. Someone with this condition tends to call themselves Hypomaniac on the internet, this should be referred to as bad. Another symptom is being short with small man syndrome, sadly this means they will get more muscular, but this just makes them look even smaller. Hypomaniacitis gives the person a tendency to attempt to make everyone laugh by using bad memes and laughing at friends. There is also a very common occurrence of extreme anger management and glorified self image.
Wow, the guy who runs Hypomaniac on youtube must have Hypomaniacitis.
