“Fanboy” is just one of over 100 words to be added to the Miriam-Webster Dictionary this year. They specifically have it defined as “boy who is an enthusiastic devotee, such as of comics or movies.” Thankfully, the more derogatory “fanboi” is nowhere to be seen.
Other words added this year that I use on a regular basis: “Texas Hold ‘Em” (defined as The Cadillac of Poker… not really), “Webinar” (a part of my job is working on these), “Edamame” (delicious), “Dwarf Planet” (not a planet of Dwarves), and “Pescatarian” (though I’ll probably stick with “Vegetarian who eats some fish.”)
damn dictionary fanbois… adding silly words like w00t and n00bz to our language.
