The literal translation of their group name KNK is "great" or "to be great".
Their fan club name Tinkerbell was picked out by Park Seung Jun while the group were watching the movie 'Tinker Bell'. In his post in the fancafe he explained, "So KNK means to become “great” people and Tinkerbells are small cute fairies! So we are Peter Pan and Tinkerbells are fairies who protect us and we will protect Tinkerbells too!".
