The Sore Loser (usually it's a sore loser, but not always) is not pleased that they lost the big game, got a bad call from a referee, or were humiliated in front of spectators. So what do they do? They decide to physically assault the offender after the game has ended and everyone's gone home. They usually intend to inflict a No-Holds-Barred Beatdown and/or Curb-Stomp Battle on the offender.
As the examples show, it usually does not go well for the instigator of this trope. Usually, it turns out to be the assailant that ends up on the receiving end, adding to their Humiliation Conga. This can serve as An Aesop about sportsmanship and accepting defeat.
Expect to see this trope in sports related media (bonus points if it's a combat sport like boxing, karate, MMA, etc). Note that this trope doesn't have to happen immediately after the contest. It can take place beforehand or in between events.
If the violence happens inside the playing area during the game, it's Unnecessary Roughness. If the violence happens outside the playing area during the game, it's Ring Out. If the fans are the violent ones, it's Football Hooligans. If the intent is to injure the opponents to hamper their skills & abilities, it's Crippling the Competition.
Anime and Manga
- In One Piece, in Dressrosa arc (specifically in the Corrida Colosseum tournament) after losing to Rebecca in the Round D match, the tournament losers tried to assault her when she's about to play in the next round.

- In Genkai's disciple selection test early on in YuYu Hakusho, she has all her applicants get lots of paper. If their paper changed color, they could start her selection trials. If not, they were told to leave. Two self-proclaimed experts angrily attack Genkai over being rejected. She promptly blasts them with spirit energy across the courtyard and into her entrance gate. (It turns out that her paper lots were not random; they only changed color if those holding them had a certain amount of spirit energy.)
- Double subverted in a later episode of Sailor Moon; Haruka wins a motorcycle race and other bikers plan to attack her. One of her more honorable opponents warns them to stay away. But later on, bikers riding in a truck attempt to run Haurka and Usagi off the road; they then attack Haruka afterwards, but she easily mops the floor with them.
- Subverted in IGPX Immortal Grand Prix. Team Satomi manages to beat Sledge Mamma, despite mechanical sabotage during the race. The team thought this was something Sledge Mamma would do, since they usually use underhanded tactics. After the race, Takeshi, Liz, and Amy are ambushed by a group of thugs who had previously hassled Takeshi. Sledge Mamma showed up behind them, leaving Satomi trapped between two. Satomi feared the worst. The thugs attack, but are quickly beaten down by Sledge Mamma. The thugs admit to being Sledge Mamma fans, but Yamma tells them that what they did was despicable.
Yamma: Sorry about that. Our fans can get a little rowdy sometimes. We just wanna beat ya, not beat you up.

- Family Guy had an episode where Peter is teaching Chris how cultured Americans are and that part of that is getting way too emotionally involved in high school football. He then teaches him that sometimes your team loses and you have to beat up the referee in the parking lot afterwards. However, in the middle of the beating, Peter realizes that the referee is an old friend of his, and the two have a pleasant conversation even as Peter keeps beating the shit out of him! He even has Chris come in and say hello, while taking over the beating.
- This has happened a number of times with combat sports competitors, notably boxing and MMA. This is not a good idea however. Away from rules, regulations and referees, brawling can lead to the combatants getting injured, maimed or even killed. Plus some sanctioning bodies may prohibit this, leading to fines, suspensions or even bans. There's also the reality of getting arrested and going to prison.
- A loss from a basketball game in Houston, Texas turned deadly when someone shot and killed one of the winning players soon after.
- This trope can happen during the game too. Manchester United star Eric Cantona took direct retribution on a fan who was heckling him during the 1994-1995 season. Cantona famously leapt into the crowd and delivered a roundhouse kick to the chest; he was banned from all football for a year and faced a criminal investigation. Man U fans still sing about this when playing Crystal Palace.
- Former New England Patriots general manager Patrick Sullivan found himself in the middle of this during the 1985 NFL playoffs when New England defeated the Los Angeles Raiders in the AFC Divisional playoffs.
