The biggest thing i’ve seen on twitter is people talking about The Celtics Basketball Team saying they are “world champions” despite just winning the NBA

It’s so stupid they call themselves that, you won a DOMESTIC LEAGUE. I don’t care if USA have the best basketball league, that doesn’t mean your world champions when you haven’t won that against international teams.

Who wins the Champions league (cup tournament for best European football/soccer teams) are always the best team in the world but I’ve never seen a team call winning that “world champions” since they haven’t faced teams from the world! I feel like it’s just American arrogance.
