*Garry's Mod specifically*
Roleplay Term.
When a large amount of minges (mingebags) join a server to constantly harass and troll the other players and staff, the purpose being to stress people out.
Usually, the causes of a mingepocalypse are:
a large group of friends,
a popular livestreamer streams and viewers want to play with them, or,
the server's IP is posted in an online troll forum, Steam group, chatroom or social media, and OP requests a raid.
A mingepocalypse is most likely to occur on DarkRP servers, as it originated from the game mode
Player: Dude, why the hell is spawn like this?
Player 2: It's a mingepocalypse, the staff are all busy with the fucks.
Player: I got RDM'd like 6 times! Do something!
Admin: It's a mingepocalypse right now, we need to focus on getting them banned.
