Extremely tight
black pants, that resemble fake leather, or maybe vinyl. Girls used to wear them early 2000-2002, and being slightly
glossy, they looked somewhat like they were made from garbage bags. Also referred to as "
gbp"
High school girls would walk around in these tight
black pants, which usually made their ass look all stretched and squished like an old ladies...someone in your group would say "
GBP" and you all knew some broad was wearing the garbage bag pants
