It'd be too much, so I will only be mentioning dramas that aired in the last 5 years (2017 to 2022)
SKY Castle (2018)
I personally think this is the most popular drama in the last 5 years
-'Mother, you have to completely trust me'
-'I'll rip your mouth off'
-Jokes about being on the top of the pyramid
-Even the OST becomes a trend 'We All Lie'~
The World of Married Couple (2022)
-'Falling in love is not a sin!'
-Han Sohee, who starred as Yeo Dakyung the mistress, became a star through this show
Penthouse (2020)
The next two seasons are not as popular as the first one, however the first season was like a syndrome to the entire nation
-'You're already trembling...^^'
-'Thief bitch'
-The scene of Cheon Seojin playing the piano becomes a hot issue in online communities
Squid Game (2021)
-'Stop~ We're all gonna die at this point!!'
-The memes are more hyped overseas than in South Korea
(Red Light Green Light, Dalgona challenge, Slap-match game, etc)
Extraordinary Attorney Woo (2022)
-'Kayak, deed, rotator, noon, racecar, Woo Youngwoo~'
-Woo Youngwoo and Dong Geurami's greetings (Woo to the Young to the Woo~)
-'I'm disappointed'
-I either haven't watched or stopped watching these dramas, but I know all the catchphrases and memes mentioned in this postㅋㅋㅋㅋ
-I only watched SKY Castle but I know every catchphrase and meme mentioned in this postㅋㅋㅋㅋ
-I haven't watched any of these dramas but I have heard all those catchphrases from this online communityㅋㅋㅋㅋ
-Whoa... I have watched every single dramas mentioned in this post except for Extraordinary Attorney Woo
-None of my friends watch dramas but I know all of these catchphrases and memes except for SKY Castle's ones...
-I can't believe SKY Castle was from 2018...
-Whoa... It's shocking how I have heard those catchphrases at least once, despite not watching any of those dramas...
-I have only watched Extraordinary Attorney Woo and SKY Castle...
-I have never watched any of these dramas but why does it feel like I've watched them...?
-'You're already trembling...^^' is the funniest one for meㅋㅋㅋㅋ
