In Korea, canned Spam (스팸) is a genuinely valued gift, often sold in premium gift sets around holidays. It is not a joke present — a tin of Spam handed between friends or family carries real warmth, inherited from the post-war era when imported canned meat was a luxury item.
Joon-hyung just told Bok-joo he hates petty jealousy and pushing-and-pulling (밀당, mil-dang) in relationships — and then immediately proved himself guilty of both by dragging her to a hair-accessory shop to replace the pin her ex liked. 밀당 literally means 'push-pull' and describes the game of playing hard to get that Koreans often talk about in dating culture.
The doctor describes Song Si-ho's condition using the term 섭식장애 (seopsik jangae) — an eating disorder involving cycles of binge-eating (폭식) and restriction (거식). In Korean university sports culture, weight-class pressure on athletes makes this particularly common, and the drama treats it with clinical honesty rather than as a side plot.
똥배짱 (ttong-baejjang) literally means 'poop-belly boldness' — it is a vivid slang phrase for the kind of reckless, thick-skinned courage that refuses to back down no matter how hopeless things look. It is usually said with affectionate exasperation, which fits perfectly here: the team is proud of their own stubbornness.
단식투쟁 (dansik tujaeng) — a hunger-strike protest — has a long, serious history in South Korean student and labour activism going back to the democracy movements of the 1980s. For these weightlifters to adopt it as their tactic is both earnest and a little comedic; they are invoking a powerful political tradition to fight for their coach.
The older brother's line — 'men and women being just friends is nonsense' (남녀사이에 그냥 친구는 개뿔) — echoes a very common belief in Korean popular culture and older-generation thinking. 개뿔 is a mild but colourful way of saying 'absolutely nothing' or 'yeah right.' The show gently pokes fun at this attitude throughout the series.
러브샷 (reobeu syat) is a Korean drinking ritual where two people interlock their arms and drink at the same time — traditionally done by a new couple to announce their relationship, or by two people who want to show closeness. Asking the professor and the reinstated coach to do one at the celebration party is a cheeky, affectionate nudge.
After 가위바위보 (rock-paper-scissors), the loser has to press their forehead (마빡, mapak — forehead in casual speech) against the winner's finger flick. This playground forfeit is so universally known in Korea that no explanation is needed between friends — which is exactly why Joon-hyung knows he has to take his punishment without complaining.
