It happens to silent and quiet people when they encounter a situation and they get irritated inside.
John: she kept asking stupid questions in the meeting and I had this Mass shooter syndrome and couldnt tell her to shut up.

Huge party typically full of teenagers and early 20 year old guys looking for a quick root. Best to go to these parties fully clothed unless you're looking at getting pregnant or paying child support for the rest of you life. Mass parties generally don't have honourable amounts of food just booze and weed. Best mass parties are hosted in halls and clubs with mean lighting set ups
Chad: " yo Harley did you hear there's a mass party on Saturday?!"
Harley: " yeah I did, ifts going to have all the bass drops and sickest lighting set ups, I heard there's going to be over 300 people!!"

Mass Formation Psychosis is when rightist traitors who didn’t know Trump LOST the election and blindly believe there is mass voter fraud based on fear without any evidence, while putting their feelings above facts and emotion above patriotism.
Toothless Ted thinks there is mass voter fraud when there is no evidence and all voter frauds found so far were all Republican righties- sounds like he is living in fear, has delusion and Mass Formation Psychosis. Law and order. Justice is coming- Trump for prison 2024. Cry more and keep being triggered by facts- Biden won, Trump LOST, BIDEN IS YOUR PRESIDENT.
