** In WebVideo/UrinatingTree's videos, Tree, a Steelers fan, argues that the Steelers were this towards the New England Patriots during the Patriots' Creator/TomBrady years. Many Steelers fans often see their team as one of New England's biggest threats in their conference, despite the fact that the Patriots have consistently manhandled Pittsburgh for a long time, and Tree points out that even though the Steelers have gone to the Super Bowl three times in the Brady/Belichick era, they never had to face the Patriots in those playoff runs.

* Meanwhile, the Cleveland Browns claim rivalries with all three teams in their division: the Pittsburgh Steelers as a traditional rivalry, the Cincinnati Bengals as an intrastate rival, and the Ravens because their team was founded at the expense of decimating the Browns franchise[[note]]in 1995, the existing Browns team moved to Baltimore and became the Ravens, and the Browns franchise was left to start essentially from scratch[[/note]]. Unfortunately, due to their...ineptness...at fielding a competitive team, those three teams have historically focused more on each other than the Browns. However, the team's major turnaround in the 2020 season, which they capped off by handing Pittsburgh a shocking playoff defeat[[note]]in addition to beating Cincinnati twice and Pittsburgh once in the regular season[[/note]], combined with ''Cincinnati'', not Cleveland, coming in last in the division for three years straight, will probably lead to the Browns being taken a bit more seriously going forward.[[note]]Or maybe not, as they missed the playoffs in 2021 while the Bengals played in the Super Bowl.[[/note]]

'''Jeremy:''' ...YOU KNOW DAMN WELL WHO I AM!

* The city of Baltimore lost their longtime football team, the Colts, to the city of Indianapolis in the spring of 1984. The fans of the team have since sported a longtime hatred of the team for abandoning them, as well as the owners of the team (Robert Irsay at first, then his son Jim after Robert passed away). Since Baltimore gained a new NFL team (the Ravens), whenever the Colts have visited, they have been introduced as the "Indianapolis professional football team" (pointedly avoiding the nickname "Colts"), among other indignities. Those in Indianapolis have no particular hatred of the Baltimore Ravens (or the city of Baltimore in general); many Colts fans don't even know there ''is'' a rivalry, and the rest simply don't care.

* In what is probably the most extreme example, [=UConn=] head football coach Bob Diaco decided to create a conference rivalry game for the team after losing their traditional rival games during the 2013 conference realignment. He chose the University of Central Florida and went on to create the [="Civil ConFLiCT"=] and have a trophy made up. However, UCF has no interest in the rivalry whatsoever, going so far as to ''leave the trophy at [=UConn's=] stadium'' when they first won the game in 2016. And with [=UConn=] leaving the conference shortly after, it seems this rivalry was more of a dead on arrival-ry.

* The [[UsefulNotes/CanadianFootballLeague Montreal Alouettes]], whose traditional rival (Ottawa) was out of commission after folding twice, had a few of these until a third Ottawa team started up in 2014. Their Labour Day Classic game (traditionally a time where the whole league pairs up in rivalry matches) shifted to an East-versus-West game against the BC Lions, a team that has no real rival, but they never treated BC as their new rival. In 2009, an attempt was made to found a team in Quebec City and have them be Montreal's rival because they'd be in the same province, similar to Edmonton-Calgary and Hamilton-Toronto. Montreal basically laughed it off and shut down their attempt, saying any bid to make another team in their province would have to go through them. Now that Ottawa has a team again, however, the fact that it's technically a new franchise hasn't stopped Montreal from igniting the old flames, probably because they're not the original Montreal Alouettes either and actually began as the Baltimore Stallions during the [[DorkAge American expansion experiment]].

* Fans of the San Diego Padres absolutely hate the Dodgers, bitter at how Dodgers fans have a habit of traveling en masse to San Diego for games and often nullifying their home-field advantage, as well as how the Dodgers are simply their closest geographical rivals in general. Unfortunately for them, their hatred can never be reciprocated, as the Dodgers tend to save all their hate for the Giants, their ancient enemy.

* The AFC East has a ton of this. Buffalo Bills fans despise all 3 of the other teams in the division, Miami Dolphins fans pretty much ignore the Bills and treat the Jets like a joke, New York Jets fans feel likewise about the Dolphins and ''really'' hate the Patriots, while New England Patriots fans treat the other 3 teams like they're nothing but jobbers. However, with Tom Brady's Main/ReignOfTerror finally ending after the 2019 season and the Bills finally ending their [[Main/AudienceAlienatingEra 20 year period of futility]] by winning the division in 2020 and 2021 this may get changed around a bit in the future.

* Rex Ryan, head coach of the Buffalo Bills and formerly of the New York Jets, seems to consider Bill Belichick of the New England Patriots to be his ArchEnemy, constantly calling him out and talking smack. Belichick, on the other hand, hardly seems to even ''notice'' Ryan, though being [[TheStoic Belichick]], it's as much the way he is with ''everyone'', not truly lack of interest (his preparation for all opposing teams is exhaustively intense and informative) -- Ryan is nothing more than the next entry on the schedule to him.

* Both fans and players of the Cincinnati Reds and Milwaukee Brewers have a bitter hatred of the St. Louis Cardinals due to the later team's constant success within their division (and for Brewers losing to the Cardinals in their only World Series appearance), but most Cardinal fans did not realize this, as they were more focused on the ArchEnemy Chicago Cubs and the [[FriendlyRivalry Friendly Rival]] Houston Astros. That was until players on the Reds (Brandon Phillips in 2010) and Brewers (Nyjer Morgan and Zack Greinke in 2011) started insulting the Cardinals. The fans became very aware of the rivalry after that.

* Meanwhile, the Cleveland Browns claim rivalries with all three teams in their division: the Pittsburgh Steelers as a traditional rivalry, the Cincinnati Bengals as an intrastate rival, and the Ravens because their team was founded at the expense of decimating the Browns franchise[[note]]in 1995, the existing Browns team moved to Baltimore and became the Ravens, and the Browns franchise was left to start essentially from scratch[[/note]].

* Boy, oh boy, where do we begin with both of the NBA teams that reside in Los Angeles? Ever since the Clippers' move to Los Angeles from San Diego in 1984, Clipper fans felt that their new neighbors, the Lakers, would be their biggest rivals. But here's the thing: While the Lakers have been historically successful[[note]]At the time the Clippers moved to L.A., the Lakers had eight championships under their belt[[/note]], the Clippers...have not. While the Lakers won championships left and right, the Clippers were designated as the little brother team, and it ''showed:'' Between 1984 and 2010, the Lakers won eight more titles, while the Clippers only made the playoffs a paltry four times in that span (1992, 1993, 1997 and 2006). When the 2010s rolled around, the Clippers slowly began to build up some respect by making the playoffs in consecutive years, while the Lakers began to miss the playoffs in consecutive years, something they haven't done since the ''mid-1970s''. By the time the 2020s arrived, the Lakers won one more title, and a year later, the Clippers finally made their first trip to the Western Conference Finals. Despite the Clippers' recent trips to the playoffs, Laker fans barely pay any attention to the Clippers or their fanbase, reserving their hatred for the Boston Celtics.

* NCAA Division 2 Lone Star Conference. Midwestern State University and Tarleton State University are hated rivals. Like, Red Sox-Yankees hated rivals. Both of them completely ignore West Texas A&M, who simply believe that both schools are their biggest rivals, and focus on each other. This even got taken to new heights in the 2012 LSC Championship semifinals (basketball), where TSU played WTAMU. WTAMU's fans even tried to invade Tarleton's side of the court. What did Tarleton do? Absolutely nothing. Not even attempt to drown them out.
** 2012's football season may have changed that. West Texas's student body "declared war" on MSU's student body in the build-up to the football game on the weekend of November 3, due to this game's winner likely winning the conference and the loser likely going to the dreaded Kanza Bowl (highest-ranked non-playoff teams go, but it's on a bad date and the weather is usually terrible). In the six teams played between the two schools' various sports teams that week, the home field advantage has been minimal, and the games have been rather violent where applicable.
