They bandwagon-jumped me from a pogo
I'm going fucking loco,

from Tyler The Creator – Colossus Lyrics on Rap Genius

Meaning

Tyler’s explaining that they jumped straight on the OF bandwagon despite not even hearing his earlier material (see previous line).

They use a pogo to do this, a popular toy which allows one to bounce up and down. This is driving him loco (crazy)! These kids jump from one new trendy thing to the next constantly; they always stick with what is being hyped out. Just to twist the knife, he references Mellowhype’s “Loco,” which the bandwagoneers wouldn’t know about, not being true fans.

As in the Yonkers bunch.
