Sigma Chi (ΣΧ) is one of the largest and oldest all-male, college, Greek-letter social fraternities. Sigma Chi was founded on June 28, 1855 at Miami University in Oxford, Ohio when members split from Delta Kappa Epsilon. Sigma Chi has seven founding members: Benjamin Piatt Runkle, Thomas Cowan Bell, William Lewis Lockwood, Isaac M. Jordan, Daniel William Cooper, Franklin Howard Scobey, and James Parks Caldwell. Sigma Chi is a part of the Miami Triad, along with Beta Theta Pi and Phi Delta Theta.
The fraternity's official colors are blue and old gold, and its badge is a white cross with emblems on each of its arms: crossed keys on the upper arm, an eagle's head on the right arm, seven gold stars and a pair of clasped hands on the lower arm, and a scroll on the left arm. In the center of the cross, on a black background, are the gold symbols for the Greek letters Sigma (Σ) and Chi (Χ). The left and right arms are connected to the upper arm by gold chains.
Sigma Chi's purpose is to promote the concepts of Friendship, Justice, and Learning; its mission statement is to develop values-based leaders committed to the betterment of character, campus and community. Sigma Chi's vision statement is "to become the preeminent collegiate leadership development organization—aligned, focused and living our core values".
On June 13, 2005, Sigma Chi was the first Greek-letter society to be honored by the United States Congress for the fraternity's 150th anniversary.1

The second largest fraternity in the nation. Based on friendship, justice, and learning. Guys who don't sweat it when people take time out of their day to be hateful on urban dictionary.
Sigma Chi 1: Hey did you see what those people said on urban dictionary about us?

Sigma Chi 2: Yea. Hate hate hate.

Sigma Chi 1: In hocs all around.

The greatest international fraternity. Founded in 1855. These guys have the biggest ragers, have the hottest sweethearts and screw the hottest sorority girls. Brad Pitt, Mike Ditka, Drew Breeze, John Wayne were all Sigs and more. DKE's are scared of Sigma Chi's cause they know sigs are the best on every campus in the nation. These guys are basically god's gift to humanity.

Sigma Chi: *stumbling out of car with a bottle of jack daniels in his right hand* I'm a Sigma Chi bro.
Officer: Oh I'm so sorry sir! please carry on.

Sigma Chi: In Hoc!
