Get the bandwagon mug.
What people will "ride" or get on when they want to be accepted, espescially in the NFL. People will get on the (Colts) bandwagon and suddenly become their fans because they are doing really good or because they have a large number of fans so they can be accepted.

People will ride a bandwagon even if they dont give a shit about football or whatever the bandwagon is.

Get the Bandwagoner mug.
In sports, someone who selectively cheers for a particular team (Team A) not because he likes them or follows them faithfully, but only because another team (Team B) that he does not like, happens to be doing worse than Team A. This person then enjoys ridiculing fans of Team B, and often will claim that they have been "a fan forever", but only for the time being, because when Team B performs better than Team A, they then go back into hiding and remain silent.
The Rudde bandwagoner hopped on the band wagon and bragged about the Padres, but only when they were doing better than the Dodgers.
