Welcome to Players Against Bunny Hopping / PABhop

Bhopping, or bunnyhopping, if an exploit in some game's physics engines that allowes a player to increase their movement speed. with increased speed comes much higher mobility, and depending on the game, that can give the player an unfair advantage.

Bhopping is found is many games, including CS:GO, CS:Source, Gmod, The Halflife series, and Quake, Payday 2, Team Fortress 2 as well as several others.

Players will often defend this by saying it is part of the game and and point out it requires skill to perform, but in many games this is still an exploit on the physics engine, and if the game isn't balanced around it it can be game breaking

Obviously it doesn't matter if it's a single player game
