a less trendy way of using 'LOL' to represent laughing out loud when chatting online. You can use capital letters to represent harder laughter, and place them in any sequence depending on the type of laugh . 'ruFF' would be used if at first you just smiled, but then realized that what you read (or typed) was indeed, pretty funny.
Colin says: "My middle name is Susan."

Tim says: "rufF"

in this case, it wasn't terribly funny, but enough to get a smirk, then at the end, Tim realizes Colin is being especially silly and is forced to laugh.

The head coach of the best and most improved team in the NHL. By far the coach that should win "Coach of the Year" for turning the Buffalo Sabres from a slumping pro hockey team into a skilled, depthed, young, and passionate team after the NHL Lockout. Also they Sabres have the best fans outta the world in BUFFALO!!!...mainly thanks for the Canadians just a few miles away who have helped Buffalo and the people of Upstate New York to love the sport of hockey.
Lindy Ruff, the coach of the Sabres.
