SFIS

A versatile acronym used in chat conversations. Commonly defined as "So Funny it's Scary!" or "So Funny I Screamed!"

Users frequently replace the final "S" with other letters such as "L" (So Funny I Laughed!) or "U" (So funny I urinated!)

As internet chatsters across the globe realize the amazing versatility of this acronym, it's only a matter of time before "LOL" becomes obsolete.

Friend #1 - "No really, you need to pluck it at once!"

Sfiso

The type of guy that likes it harder. Becareful around Sfiso's, they'll bust a handle. They have a tendency to like Lypse's tits and they enjoy SUSHAY! The quality stuff. They tend to have panda fixations and have strange fetishes for wolf furries. But I guess, if you like it, you like it.

1. Aw man, Sfiso bust a handle.
