Four ways to summarize that fanbase for me.
1 - that video
2 - I was at the last regular season game against them where they completed the "sweep" of the Oilers. You would have sworn they won the Stanley Cup. Nuck clowns in attendance were literally taking selfies of a group of them raising up 4 fingers on one hand and an 0 on the other. Basically was the greatest thing to ever happen to them at that point ever. Were in heaven.
3 - The first intermission of Game 3 in Edmonton where I believe they were up 3-1 if memory serves. Again, Nuck clowns in attendance had acted like the Stanley Cup was won. Loud celebrations, high fives in the concourse and leaving the bathrooms, etc. Basically what normal, not stupid people would do after actually winning the series. I've been to plenty of big games and plenty of rivalry games in a bunch of buildings and I have never even once seen a group of people act so ridiculous having not actually won anything. It was the first intermission.
4- 3 of those idiots flew here for Game 6 and sat in front of me. One of the three seemed to actually care about what was happening on the ice, the other two were more interested in selfies and generally acting like f***ing idiots. Left after we went up 4-1, then the cherry on top was seeing them get their asses kicked outside the arena on the YEG Wave instagram account the next day
They're a clown group of people. I don't exactly know why, but they are certainly unique in terms of NHL fanbases.
