Trip

Trip is a gameplay mechanic found in various Mario games (mainly RPG games), 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 in battle. 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 (or Bros. Items in the second Mario & Luigi game). If the tripped brother has high enough speed to move first, this condition can be instantly negated.

Mario & Luigi: Superstar Saga / Mario & Luigi: Superstar Saga + Bowser's Minions
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 and bosses such as Tanoombas, Clumphs, and a few of the Koopalings can trip the brothers with their attacks. Unlike other negative status effects, this cannot be cured with a Refreshing Herb in the original game.

Mario & Luigi: Partners in Time
In Mario & Luigi: Partners in Time, this status effect returns, functioning the same way as it did in the previous game. Since Mario and Luigi cannot switch positions like they could in the previous game, Luigi is more likely to get the status effect when an enemy touches him from behind, since he is always the rear brother. The same goes for Baby Luigi when he travels with Baby Mario without the adult brothers, and this carries over throughout all subsequent games. Unlike the previous game, only a select few bosses can trip the quartet, like Elder Princess Shroob. Once again, this status effect cannot be cured with a Refreshing Herb.

Mario & Luigi: Bowser's Inside Story / Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
In Mario & Luigi: Bowser's Inside Story and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, Trip reappears once again, and with Bowser being a playable character, he can receive this status as well. Unlike the previous two games, this status effect can be cured with Refreshing Herbs.

Mario & Luigi: Dream Team
In Mario & Luigi: Dream Team, the Trip effect makes another appearance. Gold Beanies will trip if their attacks are countered correctly, making them unable to run away from battle, and allows Mario to freely attack them for a few turns. Unlike the past three Mario & Luigi games, the status was given the word "TRIP", making it a normal status effect.

Mario & Luigi: Paper Jam
In Mario & Luigi: Paper Jam, Trip returns again, functioning the same as it did in Mario & Luigi: Dream Team. Like in the previous game, when this status effect is inflicted, the word "TRIP" will appear.

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.
