killer on a Friday
An expression signifying that you are in possession of some killer marijuana bud (kush, sour deisel etc.) on a Friday, and everything is going to be great because of that. Friday, generally being the end of the work week is a time to unwind and get ready for the weekend. What better way to unwind than with a big fat joint of some killer?
