Chances are, when talking to friends, family, or co-workers via text or IM (or, perhaps even in person), you've used abbreviations for common phrases like "LOL" (short for laughing out loud) and BRB (an acronym for be right back). Now, I asked you where OMG -- short for "Oh my God" originated, what would you say? Perhaps you may point to the internet chatrooms that became popular in the 1990s through services like America Online. If you were born in the 2000s, you might guess it started with texting or email. Actually, you'd have to go back further -- to the first half of the 20th century, that is. Indeed, "OMG" dates back to World War I.

LOL is what we employ to indicate that something the other person tells us is amusing in some way. You may actually let out a small chuckle, but really: How often do you hear people laughing aloud, let alone when chatting with someone online? Maybe we just haven't come up with the right acronym that captures feeling amused. A Faceb...
