A phrase commonly used by the gymcel, incel, and gigachad. Because a Sigma Male is equal to an Alpha Male, and the Sigma sits outside the socio sexual hierarchy, he is free from the relationships and burdens that come from being the top of the pack. It is for this reason that fellow Sigma Males will use, "Stay Sigma" as a greeting, compliment, etc.
Sigma: "I'm tired of this party, I'm leaving."
Chad: *salutes*
Sigma: "Stay Sigma Chad, Stay Sigma"

Tri Sigma, or Sigma Sigma Sigma, is a sorority of women who are regarded across the nation as role models for their communities.

With over 100,000 members worldwide, Tri Sigmas are well-known for their class and charisma. They uphold the values of power, wisdom, faith, hope, and love in all they do.

On college campuses, Tri Sigmas are usually recognized for being extremely involved in other extra-curricular activities and extremely academically successful.

Unlike other sorority girls, Tri Sigmas place a high emphasis on sisterhood, service, school, family life, spirituality, and leadership. While partying is a facet of any sorority, it plays second fiddle for Tri Sigmas, who usually have enough on their plate making the world a better place!

Tri Sigmas are well-known for being some of the most attractive girls across the nation, as well as the most genuine and likable. For this reason, fraternity members and/or athletes often select Tri Sigmas as their dates of choice for social events.

Tri Sigmas are certainly the best of the sorority women. Many who are denied a bid from Tri Sigma rush another sorority unhappily or wait patiently to see if they can eventually be chosen for the select few.

The Sigma Kappa Sorority back then, in the early 1900's, was only for the wealthy, skinny, and so called perfect girls the frat boys were notorious of. If a frat boy thought of the perfect, mostly blonde, sorority girl, they thought of a Sigma Kappa girl. Today Sigma Kappa isn't as popular as it used to be in the west coast but has conquered schools of the preppy mid-west and east like the University of Kansas, State University of New York at Fredonia, Albright College, University of Michigan, Maryland University, The U at Minnesota, Chico State University (in California) and Pen State. Sigma Kappa's are top-tier at these universities. If you aren't a Sigma Kappa at these schools, you're probably low to mid tier which is good but not great. These sorority girls have class, pretty faces, hot bods, social essence, are popular, service oriented and quite the partiers at these colleges of course. These girls are carry confidence, purity, and the self-evidence that girls will run the world. With grades at an average of 3.5 nationally, these girls have brains and have personalities that will make you get on your knees. Find a Sigma Kappa girl and she'll welcome you to her mystic bond as so will her sisters.
Ben(Frat boy): Did you see those girls at the bar night? They were so perfect I can't get them off my mind bro.
Nick: Oh yea dude I think those girls were Sigma Kappas.
