Yo, I just bought an ounce of some good kryptaconalite (weed) so that we could smun and get blasted!
Smunning inside a small, closed, non-ventalated area is fun.
Shit, smunning gave me a mean case of munchies.
In Amsterdam it's legal to smun, so I'm moving to Amsterdam, baby!
Short-hand for the word floccinaucinihilipilification, meaning the estimation of something as valueless (encountered mainly as an example of one of the longest words in the English language).
