When I frst saw the name of this Bang Bus update I too was like wtf is Hialeah Chongas I did a little googling and found it on Urban Dictionary you can read that entry HERE.  It basically means a Mexican girl who is kind of a slutty dresser and from what I saw in this video just slutty in general.  The guys pick her up in the bus and start showering her with money, and she does everything they ask and more.  The girls name is Nadia Lopez she has a gorgeous round ass and some nice big boobies watching her fuck was real fun.
