Whenever a typically bad college football team becomes uncharacteristically good for one season (usually involving a 12-0 regular season record) to the point where you'll hear its fans chanting this phrase hoping that their team will play Alabama-only for their souls to be crushed as said team gets demolished by Alabama when they do eventually play them during a bowl game or some sort.
(college football fans when their team is on a hot streak)
"WE WANT BAMA, WE WANT BAMA"
