When your very tired from partying the night before with a friend who is an avid runner and has more energy than a uranium fuel rod and he calls you because you missed your 0600 showtime for a 5 mile run.
Phone rings “ring ring ring, dude in bed answers- Hello? Caller says in a dubious voice- “Hey what you doing man? Dude in bed responds, “Duuude, I’m ruffling in the sheets man”. Ruffling in the sheets? WTH does that mean? I’m half way between being ready and going back to bed which is better than being in bed and not being ready!
