A Texas Delt is a fraternity member at the University of Texas who is viable to getting drunk and/or stoned every single night and then proceeding to make questionable decisions; they are the coolest of the cool.
Joe - "Hey man, im a freshman at UT, do you know any cool guys?"

Brock - "Yeah there's only a few guys that are cool here, and they are the Texas Delts."
