pentagon always release or make songs that shows how much they love korean culture/language

감이오지 (can you feel it) 감 means "persimmon" or "sense". they teased us using persimmon bfr. the title album was "five senses" and 감이오지 can also translated as "five senses"

청개굴이 (naughty boy) if we don't know korean's fable of frogs we might not know the connection between frogs & naughty boy

here's a video abt the song explained by a korean if you haven't watch:

신토불이 originally means "belief that domestic farm products are the best" but it's actually an acronym of "Exciting Saturday Firey Night" they also uses lots of wordplay in the lyrics. There's even once on VLIVE hui teased yuto saying it's a word that he made himself

Fantasystic the "동구 밖 과수원 길 길 길
아카시아 꽃이 활짝 폈네요 woo ah woo ah
동구 밖 과수원 shot shot shot" and "아카시아 꽃이 활짝 폈네" is actually a lyrics from korean drinking game songs i also only recently found out about this

the 신토불이 one is actually on pentory!!

"귀신 씻나락 까먹는 소리" it's an idiom, literal meaning is "the sound of a ghost peeling and eating rice seeds" which is... a nonsense so it means "a loud of nonsense/preposterous nonsense"

They also uses their own catchphrase

저두요 (JDIY) 저두요 literal meaning is "Me too!"/"count me in!" but they translated it as "just do it yo!" their own catchphrase. the song itself shows their own stories from trainee life till now and "let's have fun till the sun rises!"

SUMMER "만들어보자 평생 남을 추억 하나 (추억 하나 get)"

"추억 하나 get!" or "one memory, get!" is hongseok's catchphrase everytime he collects new memory with the members

and ofc Round 1 & Round 2 which is full of their inside jokes
