Treinta y dos Coast to Coast
32 on the 32"
32-bit ( Best In Tournament)
The Cold 32 (I’m ref to the freezing temperature of water—see what I did there?)
Eeeeeeh that’s all I got, hey I tried!
The 32-Skidooers since they made their opponents skidoo/leave quickly.
The fifth power.
I still find the rhyming of “Great 8” more aesthetically pleasing than the alliteration of “Elite 8.” 
Elite 8 isn’t trademarked for the Division I tournament so much as it is the Division II equivalent of the Final Four - eight teams advance to the final site.
