No, it’s an inside TAMU Corps tongue and cheek thing said in jest. Cadets there refer to band queers and homo yell leaders with regularity. I seriously doubt any of them support the homo group mentioned, except for the few closet homos in the Corps.
I've NEVER heard that *joke*, ever. I don't know what your problem is with TAMU, Corps or the Fightin' Texas Aggie Band, but you've crossed the line.
It IS NOT a TAMU joke, so don't use that as your excuse.
