1. A member of the Delta Delta Delta sorority. Like many sororities, the reputation of the particular Delta Delta Delta chapter varies depending on the college or university to which the chapter belongs. Generally sorority girls are thought to be wealthy, priviledged and snobbish, but that too varies with the individual.

The use of the word Tri-Delt can be either complimentary or derogatory, depending on the intent and outlook of the user.

sexy, classy and fun. Always the life of the party and always envied. While the quality of the girl varies from college to college, tri delts are generally amazingly attractive. They have an amazing sisterhood and are always there for each other. Always dressed in polos, but never pop the collar :)
