To be fair the nicknames are Aggies and Maggies. Also the A & M in Texas A & M no longer has any meaning. The Texas Legislaturers passed a bill some years ago, changing the name of several state schools and in the bill they actually changed the name to Texas A & M without defining the A & M meaning that in Texas at least it no longer means Agricultural and Mechanical. They felt that since the university had such a wide curriculem and offered degrees in so many fields that the name was no longer appropriate.
My son is a junior at A&M so thats why I know any of this.
Also as a really weird trivial fact: As of a couple of years ago a special program at A&M that focuses on computer generated effects as in those used in movies and animation had the largest number of graduates working in that industry. They worked for Pixar, Disney, Dream Works etc. It's a highly competative program that only accepts something like 100 students a year.
