powerfaded
Being extremely drunk/high/whatever. For when using the term "faded" just doesn't accurately describe how you're feeling.
Fuck dude, I smoked like four bowls and drank a couple of 40s. I am POWERFADED.
Powerfade
When you don't want to say goodbye to your friends at the end of the night, mainly because you hate the annoying "why are you leaving", "just stay a little longer", "I'll miss you already", or "don't drink and drive", etc, you decide to leave without saying a word. Also, you are very drunk and it's time to just piece out.
Sarah: Where's Ian?!
Molly: I think he left....
Ty: He just pulled a powerfade
