It´s hard to choose. I love Refresh, Sunny, Eye Trip, Seven Sunny Days, Teddybear Crisis, Every day is a Saturday, The 86 ext. But if I had to choose one that really stands out it has to be Network. The vibe in that movie is unbeatable, gives me chills at times.
you have obviously never got drunk, grabbed both your nuts and squished them to the top of your dong, took a picture, sent it to everyone you knew and said "call 911, my penis is on upside down again".
