If someone says they went to BYU I automatically assume BYU in Utah.
Similar to Texas, if someone says they go to UT I automatically assume UT - Austin, not UT-Dallas or UT- Arlington, UT-El Paso, UT-Permian Basin, UT-San Antonio, UT-Texas Rio Grande Valley, or UT-Tyler. But if they didn't go to UT Austin it's not a big deal...
EDIT: Oh, UT also likes to play inception. There's the UT sister campus in Tyler. So, UT - Tyler. But then UT - Tyler has a Palestine campus. So there's UT - Tyler, Palestine campus.
"I go to UT."
"Oh, UT Austin, cool."
"No, UT Tyler."
"Oh cool, I grew up in Tyler."
"No, UT Tyler Palestine campus. I live in Palestine."
"I... ok."
