@Wetrix I dont buy it for a second, especially considering that the prison-origin story has mutate several times since its original telling. Used to be explained because belts werent allowed in prison, now its explained as an explicit initiation rite. Neither seem plasuable to me and there is no good source linking it to prison.
Earliest evidence of it was from the skating and hip-hop communities in the 90's. Its connection with hip-hop may havee made people assume or make up a story about prison as a result. It seems more likely it was just artists dressing absurdly on stage, as they tend to do, and people emulating it.
My guess: it’s a rumor started by someone who (understandably) HATES that ridiculous style for the sole purpose of trolling them. @freemo @Wetrix
