Gwang-bok spitting on the ground after the confrontation is a classic Korean gesture of utter disgust and dismissal — the physical equivalent of saying the whole situation is beneath him. It's a common bit of body language in Korean dramas whenever a character wants to show they feel wronged or disrespected.
Gwang-bok's complaint about not being able to use the bidet without pain is a nod to how standard bidets (비데) are in Korean homes and public restrooms — far more common than in most Western countries. Many Koreans consider them an everyday necessity rather than a luxury, so his lament lands as both funny and genuinely pitiful to a Korean audience.
불닭발 literally means 'fire chicken feet' — chicken feet braised in a very spicy red-pepper sauce. It's a beloved Korean snack and street food, often eaten at pojangmacha (street tent stalls) late at night. Bong-soon's mum buying her favourite comfort food is a very Korean way of showing maternal love without saying it directly.
Min-hyuk references 주짓수 (jujitsu/BJJ), a grappling martial art that became very trendy in Korean fitness culture in the 2010s. The joke is that Bong-soon, who has supernatural strength, instantly reverses every technique on her trainer without breaking a sweat — the comedic gap between the sport's reputation for technique and her raw power is the whole punchline.
나와바리 (nawabari) is borrowed from the Japanese 縄張り and means a gang's claimed territory or turf. It's standard vocabulary in Korean crime dramas and real organised-crime circles, so the thug's threat to 'clean up the nawabari' signals he sees Bong-soon's neighbourhood as belonging to his crew — and her presence as a direct challenge to that claim.
'해리가 샐리를 만났을 때' is the Korean title of the 1989 American film 'When Harry Met Sally'. Min-hyuk uses its famous thesis — that men and women can't truly be 'just friends' — to nudge Bong-soon toward reconsidering what her friendship with Guk-du really is. Quoting a classic Western rom-com this way is a popular shorthand in Korean dramas for characters who are too embarrassed to speak their own feelings directly.
Mi-hwa casually name-drops the Swiss-British philosopher Alain de Botton (알랭 드 보통), whose books on work, status, and love are bestsellers in Korea. His 'The Pleasures and Sorrows of Work' and related essays resonated deeply with Korean readers navigating intense career pressure, so quoting him here marks Mi-hwa as an educated, thoughtful person — which is exactly the contrast the scene is playing for when the neighbourhood mums can't quite pronounce his name.
다찌마와리 (dachimawari) is another Japanese loanword (立ち回り) meaning a coordinated group fight or rumble — the kind of brawl where everyone surrounds one target. In Korean gangster culture and cinema it describes an orchestrated mob beating, so 'Charles Go' announcing it as the grand strategy gets a laugh precisely because it's dressed up in MBA jargon when the plan is just an old-school street gang pile-on.
Grandmother Bong-soon's recorded video uses the phrase 천지신명 (cheonjishinmyeong) — the spirits of heaven and earth — to describe Bong-soon's strength as a divine gift rather than a curse. This framing draws on Korean shamanistic and Confucian belief that extraordinary power comes with a heaven-appointed purpose, which is why the grandmother's blessing feels so emotionally weighty: she is giving Bong-soon both permission and a sacred mandate.
보이스 피싱 (boiseu pising) is a massive and very real problem in Korea — scammers phone victims pretending a family member has been kidnapped or is in legal trouble and demand immediate cash transfers. The scam is so widespread that it became a cultural punchline, which is why Gyeong-shim immediately recognises the pattern. The twist here is that the gangsters genuinely thought they were being clever by copying a tactic usually run by call-centre fraud rings.
Bong-soon pulling out a handful of ordinary 호두 (hodu, walnuts) as her weapon of choice is a callback to a recurring gag in the show: walnuts are sold as brain-healthy snacks at almost every Korean convenience store and market stall, making them the most mundane object imaginable. Using them to threaten an entire gang turns a wholesome snack food into a punchline about her effortless, almost absurd superiority.
