The 11th oldest fraternity in the world established in 1847. They're highly selective with only 4,000 actives and 55,000 brothers worldwide as of 2019. They can only be found at top tier universities. They were the first fraternity to create install chapters in both Canada and the UK.

They have a rep of being athletic business and poli-sci students. This tends to attract snobby dudes.

Zeta males have balls of literal titanium. They state the obvious and don't give a fuck if you get offended. They are 2 levels above alpha and 1 level over Sigma.

basically a 'Zeta' but she doesn't quite know it.

A 'Fine' female who dresses it down, (without knowing), and doesn't really know her potential or natural beauty
She's a bit of 'a cheeky zeta' that one.
