Is it when you've been in the shower for about 90 seconds and the water juuust has worked its way into your muscles and your back can magically slump a little bit more than usual so your head goes *bonk* onto the tile wall?
Is it when you wake up with a gross feeling in your head and find you have one more beer in the fridge, just when some awesome show is coming on TV?
Is it when you have been working for like 15 hours and you can talk someone into walking on your back until you pop every one of your vertebrae joints, including the atlas-axis one, and they go 'oh shit I just broke your neck' and you go nahhhhhhhhhhhhhohhyeahhhh
Is it sleeping in fresh clean sheets?
Is it the feeling of grated coconut mushing between your teeth and the sound it makes when you crunch it under your molars?
Is it when you tell the funniest deadpan joke in the woild with the best timing and make someone laugh so hard that they don't make any laughing-noise for like 6-7 seconds but their face is beet red and they're just kind of jiggling until they can control themselves enough to actually laugh normally?
Is it .......
What is your favorite feeling in the world? I'm still thinking what mine is.
