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 :)
see that sexy girl drinking all the boys under the table but still maintaining her composure? yeah shes a tri delt.
