Trip

Trip is a gameplay mechanic found in various Mario games (mainly RPG, and Mario-related games.

Mario & Luigi series
In the Mario & Luigi games, it is a status effect. Some enemies can make Mario and Luigi trip. If a Mario Bro. trips, they will make a noise and they will fall on the ground, flailing until it is their turn, or if the enemy attacks either tripped bro, meaning that the tripped bro cannot dodge or counterattack either. This status effect also prevents the player from fleeing and using Bros. Attacks. If the tripped brother has high enough speed to move first, this condition can be instantly negated. This status effect cannot be cured with a Refreshing Herb in the first two Mario and Luigi games.

In Mario & Luigi: Superstar Saga and Mario & Luigi: Superstar Saga + Bowser's Minions, if an enemy hits the rear brother, the brother will begin the battle with this condition. Enemies such as the Tanoombas can trip the brothers with their attacks. Since Mario and Luigi cannot switch position in the subsequent games (Luigi is always in the back meaning he is more likely to get the status effect), enemies make Mario or Luigi trip if they hit them in the rear.

In Mario & Luigi: Dream Team, the Gold Beanie will trip if the attacks are countered correctly. Unlike the past three Mario & Luigi games, the status was given the word "TRIP", making it a normal status effect. This also happens in Mario & Luigi: Paper Jam, Mario & Luigi: Superstar Saga + Bowser's Minions and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey.

Super Smash Bros. series
In Super Smash Bros. Brawl, there is a random chance that players can trip if they attempt to initiate a ground-based move such as ground attacks or running. Once players trip, they can get up normally, by rolling, or with a weak attack. Banana peels and Tingle (spawned with an Assist Trophy) can induce tripping, however, and some moves have a random chance to trip the player. Random tripping is removed in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate, but can still be caused by some attacks, items and Assist Trophies.
