Used to identify a player in a multiplayer video game who primarily uses melee weapons, such as a sword or hammer, and runs into the enemy players with the intent of killing them, regardless of their amount of health, current position, or current distance.
This act usually gets the "Reinhardt Syndrome" player eventually killed. However, they never learn from this mistake and continue to run into the enemy team again and again.

One popular game, known as Overwatch, is known for its abundance of "Reinhardt Syndrome" players. In the game, a character named Reinhardt is equipped with only a hammer and shield. Hence the name "Reinhardt Syndrome".
Our teammate just ran in with that stupid hammer and died, so he must have Reinhardt Syndrome.

When a character runs into the enemy team without any support, healers, or other teammates to help them, and then instantly die. Mostly used in Overwatch 2.
Teammate 1: bro, that Reinhardt just charged into their frontline and instantly died. Teammate 2: He just has a really bad case of Reinhardt Syndrome, don’t worry.
