According to the Massachusetts-based Merriam-Webster Inc. it's like saying "yay". They say that "w00t" (spelled with two zeros) reflects the lingo used by the young generation. Visitors to Merriam-Webster's Web site were invited to vote for one of 20 words and phrases culled from the most frequently looked-up words on the site and submitted by readers. "w00t" was named word of the year. Next in line was the word "facebook". Facebook means to add someone to a list of friends on the Web site Facebook.com or to search for people on the social networking site.
