NBA bandwagon
when an nba fan is a fan of a specific player only, not the team. His/her loyalty stays true to said player, but jumps from team to team depending on where said player demands a trade to. They are considered a NBA bandwagon fan.
"Yeah man i've always been a lakers fan! That's my team!"
"Shut up man, you're just a Lebron fan. Stop being a NBA bandwagon fan."
