My understanding of this "fashion" was during Jail time only 3 sizes small medium and large.... most prisoners wanted to look bigger that life...
Then is just carried onto the streets....
This can be seen in some old movies...
Top three chain jerkers,
1-Unmuffled jake brake,
2-Bass loud enough to hear in my car.
3-Seeing another mans ass.
4-Smokers throwing butts out moving autos.
maybe not that order...
