A few guys get together. They start drinking some kind of alcohol in small glasses (preferably hard alcohol). They throw on a cheesy DVD and don't really watch it but talk through it. If they see something good in the dvd, one or all of them yell out, "Ah Puerto Rico...uh ohhhhhh!!" and then drink.
Hey Steve... tell Mark that tonight we will have a "Ah Puerto Rico...uh ohhhhhh!!"
