Your justification for taunting weaker opponents falls under the category of a non-sequitur logical fallacy--your argument's reasoning (or lack there of) does not follow a logical conclusion. Your argument would, therefore, be framed as such:
Premise: Minnesota Gopher basketball and football teams have only won 2 of 76 Big Ten Titles.
Minnesota Gopher Fans don't properly "taunt" their opponents.
Conclusion: Minnesota Gopher Fans lack of proper "taunting" technique is the reason their basketball and football teams
don't have more Big Ten Titles.
But hey, who said all Gopher Fans have to be logical, intelligent human beings.
