ICP (Insane Clown Posse) first began to call themselves Juggalos and eventually they extended the phrase to include all of their most loyal fans. The song "What is a Juggalo" was perhaps the first attempt to actually define the term. The song is very vague and essentially describes a person who is crazy, doesn't care much about society's norms, and acts anyway he pleases. (I use "he" here because females are called Juggalettes.)

Juggalos consider themselves extremely loyal to ICP and have often acted in irrational ways on certain occasions. When ICP's video "Let's Go All The Way" was released on MTV, Juggalos went to the streets of New York, in masse, to get MTV to play the video on the top 10 countdown. Even though the ICP fans were only standing around with the other fans that were on the street, MTV called up the NYPD and had the ICP fans removed. The police claimed that New York had a law prohibiting "clown makeup" on the streets. Situations like these only make ICP fans that more rabid, for they feel if they are causing that much of a reaction, then it must be a good thing.
