"There's nothing hotter than an otter!"
Regardless, we commonly refer to ourselves as "otters" similar to how Golden Bears at U.C. Berkeley refer to themselves as "bears."
Our mascot's name is Monte Rey.
We refer to groups of fans or students as a "raft," which defines a group of sea otters at rest atop a kelp forest. Example: The student section has a raft of otters watching the game.
Every year we have a homecoming event called The RAFT, which stands for Reunion And Family Traditions.
Our mascot is frequently found at sports events on campus, which are named in his honor.
