Lee Hee-ra explained 'Hakooshi (hakooshi)', which refers to a fan who likes the entire team, by linking it to the expression 'all-fan'. She also mentioned 'Menkara (member color)', which refers to a member's color, and explained it by linking it to 'Penra (fan light)', which refers to a lightstick having the color of a specific member. She then explained the usage of the terms by constructing a sentence: 'I went to a Riribe (lily event) holding my oshi's menkara penra', describing a situation where a fan who likes a specific member participates in an event holding a lightstick of that member's color.

From 'Doreka' to 'Totoi', abbreviations and neologisms used by fans

Lee Hee-ra introduced 'Doreka (doreta card)', an abbreviation for cards that come out randomly, and 'Oshinui (oshi nuigurumi)', which means a favorite character doll. The term 'Pansa', an abbreviation for fan service, was also mentioned.

In particular, she presented 'Totoi' as a recently used expression. In the conversation in the video, this term was explained as representing the feeling of 'wanting to cherish something because it is so precious and cute'. Additionally, she conveyed the emotional state felt by fans through the expression 'Mero-mero (meromero ni natcha)', which is used when something is so good it feels like you are melting. Finally, she concluded the lesson by mentioning 'Biju (visual)', which means having outstanding looks.
