Sigma Kappa

National sorority guaranteed to have the hottest girls at all the local universities you've never heard of (plus a couple big name schools, i.e, Berkeley, UPenn, Florida, etc.). Powerhouse of Playboy pinups and low-budget porns. The sorority that dropped your fat ass during rush.

Sigma Kappas do not drink. They may smoke, they may chew, they may go to bed with you, but Sigma Kappas do not drink.

sigma male 

Male type falsely believed to be on the same level as the Alpha male type. Other definitions call Sigmas loners who like to violate the norms of society, and while these aren't necessarily false, they don't tell the whole story.
While exhibiting traits of physical and professional power commonly attributed to the Alpha, unlike alphas, Sigmas are at the bottom of the sexual hierarchy, as they are known notoriously for hating all women.

Generally an asshole, especially to women and otherkin (minorities). Unironically uses the Virgin and Chad/Cringe and Based memes in the context of their personality traits versus traits of others. Sigmas are ever prevalent in 2021 with the advent of the Sigma Male Grindset videos, usually involving Sigmas doing things that are generally looked down upon (such as erasing random user's drawings in VRChat and then leaving, or insulting random women) and then stating a moral or rule to be learned from the video if one wishes to become a Sigma Male.

P1: That guy on the leg press seems like a Alpha Male.
P2: No, he's a Sigma Male. I can hear him blasting the Cyberpunk soundtrack through his Airpods from over here, and he's given like 5 women the bird for getting within 5 feet of him.

Sigma Male 

The answer to the question: "What happens when you combine an unrealistic idea of manhood with an insecure male midwit in an environment in which feminism has won the culture wars?" These men combine the worst parts of maleness (compulsive need to dominate weaker people, overall rapey vibes) with the worst parts of femaleness (moronic spirituality, manipulativeness). Luckily, they give off such strong "I'm a sad loser" signals that they're easy to avoid.

As an aside, this type of man serves a valuable role in prisons, because he's unlikely to kick up a fuss about being fucked in the ass. He's the type of person who deludes himself that "the prison bitch is the sigma to the ass-raper alpha". He serves as a receptacle for male sexuality, and he can also help in a fight if he has to. This helps keep the peace among lifers.

Person A: George meditates and says mantras for an hour before he goes to the college bar to hit on drunk teens.

Person B: Yeah, that's because someone who runs a Sigma Male YouTube channel told him he should do that.

Sigma Male 

Introverted alpha bro, and usually your roommate who hates everyone in the town he now lives in because he rarely goes outside, yet has many concrete opinions on things he's never experienced. "I dont need anyone else. I only need myself," type beat. However, they moms give them boxes of food and work 10-20 hours a week. Not all sigma males are silver platter, though.

Their romance relationships are short lived since they rarely see past the bridge of their nose. Will stand in your doorway and monotonely talk about culturally appropriating a native Peruvian tribe for aesthetic purposes only, and will tell you to take 5ml of crab salt and lake soot with your protein shakes because Joe Rogan made an ad for it. Then proceeds to take meth molly after his DMT trip. These mf think this is creative mode, while we all playing on survival.

My roommate just got back from an ayahuasca trip, and he will NOT stop listening to Joe Rogan. He also bought some raw sheep hide on etsy after he found out he's 0.08% Peruvian from Ancestry.com. His Toyota Tacoma plates say Cali and I'm worried about whether his mom is coming to drop off his food today because he hasn't turned on the blender in over 5 hours. He's soooo Sigma male.
