Using an acronym with two different meaning Normally the using of the acronym is pretty useful to associate a business with a company. However, it can generate an unwilling situation if the same acronym is used to opposite meanings. I read an article where the World Taekwondo Federation has been faced an uncomfortable issue related to their acronym: WTF. It is a slang so much used in social media as Facebook, Twiter. Your meaning can be considered as a rude sentence (What The Fu**) and there are concerns from Taekwondo Federation worldwide. To change it there is a study to rebrand this acronym to "FT". It is an enough solution to follow through with the idea of spreading this martial art among young people. Nowadays it is important to be aware of what is going on in social media. We have a kind of new lingo in the virtual world and a new acronym can spread quickly like a virus and thus can generate an unpleasant situation as related above.
