I'm genuinely curious, is there anywhere that shows that Texas came up with the term? I tried looking it up and couldnt find anything.
Obviously I'm on a Texas website so I'm not here to be like "YOU'RE WRONG, LSU IS DBU" it's a pointless argument. You want to say Texas is DBU, go for it. Not here to change minds. It's the same on LSUs message board, everyone over there will laugh and think you're all crazy for thinking Texas is DBU. But I will say this, on websites that have multiple fans of all teams like CFB on reddit, amongst other fans if you go there and as who DBU is, it's about a 95% they'll all say LSU. With some Texas, FSU, Florida, ODu mixed in. But most other fan bases outside of the biased schools fanbase would say LSU.
That could just be due to LSU being more successful recently. Also I'm a die hard Earl Thomas fan. So I'm not strictly biased to the LSU side.
