A combination of CHAmpagne and COcaine. Not the only way to party but the preferred method of ballers around the world.
Dom P and Cristal popping all over the place and huge line for the bathroom stall = Chaco night
Friend: Dude why the fuck are you calling me at 8am?
Baller: Sipping Dom P and doing lines off the table back in my suite with 20 hot ass chicks we met at the club last night, wanna join us for some chaco?
Baller #1: Damn this hangover is no joke
Baller #2: Fucking chaco...
