LOL no im not sure what it means exactly.. I clicked on this because it reminded me of a camp i went to with 프렌즈 and when we were siting around the 불, 화재 the older guys were giving people weird nicknames and they gave my friend Daniel the name "gaggles" LOL :P
Yes. It is a school based e-mail that most schools have for students to use. It is very 안전한, 안전 adn most schools like it because the teachers can read every e-mail that a student sends 또는 recieves.
