Sigma Chi

The Aggie (Texas A&M) version of frats. White or whitewashed, cultish, racist, preppy, wealthy, coke-ridden, conservative, WASPy, and overall entitled and annoying frat. Think my daddy is a lawyer or Touch me and my Daddy will sue core. Somehow all become successful businessmen or lawyers.

Anytime I hear a sigma chi say in hoc, I want to choke myself

“Erm, what the sigma,” 🤓

“Literally shut the fuck up.”
