The term given to joining a team's proverbial bandwagon during the later parts of the season and or playoffs. This means becoming a fan when you previously were not, even if that means for just a few days.
"Dude, doesn't look good for the Jazz."

"I know. But I can't stand the Lakers. If they win, I'm hopping on the Suns fanwagon."
