The Utahns here dealing with UtahPAC12 fans locally the past decade+ aren't laughing at any use of the logo. When a BYU shirt has the Big 12 logo, that's fine. The joke is when the conference logo is the only logo and it is your fandom and identity.
Exhibit A... picture from the streets of Salt Lake last fall. Is this the official PAC12 trailer? No. It's a Yewt. The person has no fan identity as a fan of the University of Utah. The identity is 1) hates BYU and 2) PAC12... with a small reference to Utah via the license plate/cover.
