Edmonton Oilers fans crowned most foul-mouthed supporters in the world
Edmonton Oilers fans have earned an f-ing hilarious distinction.
Oilers supporters are the most foul-mouthed sports fans in the world, according to a new study from Action Network, which ranked more than 200 fan bases across 10 major sports leagues.
The analysis examined more than 9.7 million comments from the Reddit communities of 205 professional sports teams throughout 2026. Researchers looked at the percentage of comments containing at least one swear word, with Edmonton fans coming out on top of the entire ranking.
A whopping 17.89 per cent of comments from the Oilers’ subreddit contained profanity, giving them the highest percentage of any fan base included in the study.
But while the Oilers finished first, they weren’t the only NHL team represented near the top of the rather questionable leaderboard.
The Dallas Stars ranked third overall, with 15.44 per cent of their comments containing swear words, while the Boston Bruins weren’t far behind in fourth at 15.33 per cent.
La Liga’s Athletic Bilbao finished second overall, with 17.17 per cent of comments containing profanity, while AtlĂ©tico Madrid rounded out the top five at 15.17 per cent.

In total, three NHL fan bases cracked the top five, giving hockey fans plenty of representation on the list.
Not every sports fan base was quite so colourful with its language.
The St. Louis Cardinals were named the most polite sports fans in the study, with just 3.13 per cent of comments on their subreddit containing swear words.
The Baltimore Orioles (3.37 per cent) and Washington Nationals (3.47 per cent) rounded out the top three, meaning all three of the most polite fan bases came from the MLB.
The study also included the NFL, NBA, MLS, Premier League, La Liga, Serie A, Bundesliga, and Ligue 1.
While the findings don’t necessarily mean Oilers supporters are the most foul-mouthed fans in person, their online reputation is now pretty difficult to dispute.
