A large social fraternity founded on February 26th at Vincennes University. Today, with chapters all over the U.S. and Canada, over 88,000 Sig Pi's, and it's headquarters in Brentwood Tennessee, it is a great fraternity, with brotherhoods lasting long after one receives their diploma.

Far better than SAE or TKE, they have no rivals.

Sigma Pi or die!

I Believe.
Man, those Sigma Pi's at Loyola University Chicago are the shit! They throw the best parties, have the best gpa's, and just basically have their shit together. They don't suck dick or date rape girls like those other frats.
