Mean Sober Friend. Someone, in a group of people drinking and having fun, that is unhappy and angry.

An obscure transformation fetish webcomic on DeviantArt that has incredibly deep and in-depth lore for some unexplainable reason.
"MSF High is such a weird read. On one hand, it's clearly made by and for transformation fetishists to rock their socks off to, but on the other hand the lore is actually super well written and really in-depth."
