Choose Your Spice Level
Not everyone is ready for the hardcore stuff. Our 4-tier system ensures you know exactly how offensive a word is before you accidentally insult your boss.
Level 1: Mild (순한맛)
Everyday slang used on TV and with friends. Safe to use in most casual situations without causing a scene. Think "Awesome" or "OMG".
Level 2: Moderate (중간맛)
A bit edgy. Use it with close friends, but definitely not with your parents or teachers. Mild swear words fall here.
Level 3: Strong (매운맛)
Explicit and offensive. You'll hear this in gangster movies or during heated gaming sessions. Proceed with extreme caution.
Level 4: Extreme (극한맛)
Censored on TV. Highly derogatory. We teach you these so you understand when someone insults you, not so you can use them.

Korean Slang Examples 👀
A sneak peek at the Korean slang words and expressions you'll master. This is just the beginning.
잼민이
[jaem-min-i]
"Jaem-min-i" is a Korean slang term originally used to refer to elementary school students in online communities and gaming platforms. It carries a derogatory nuance, specifically targeting children or individuals who act immaturely, lack basic etiquette, or throw tantrums online. Today, it is widely used to mock anyone displaying childish and obnoxious behavior, regardless of their actual age.
바보
[babo]
A common Korean word meaning 'fool', 'idiot', or 'stupid'. While it can be used as a mild insult to criticize someone's lack of intelligence or foolish behavior, it is frequently used in an affectionate or playful manner between friends or romantic partners.
멍청이
[meong-cheong-i]
A mildly offensive term used to call someone an idiot, fool, or stupid person. It is often used jokingly among friends, couples, or toward children, lacking the severe maliciousness of stronger curse words. However, it can still be insulting if used seriously toward a stranger.
허접
[heo-jeop]
It refers to someone who is poorly skilled, incompetent, or a noob at a particular task or game. Originally derived from a word meaning shabby or of poor quality, it is now widely used as a lighthearted insult among friends or gamers. It carries a teasing or mocking nuance rather than a deep sense of malice.
또라이
[ddo-ra-i]
A slang term used to describe a crazy person, weirdo, or lunatic who acts irrationally or outside of social norms. While it can be a genuine insult directed at someone causing trouble, it is also frequently used playfully among close friends to call out eccentric behavior.
똥개
[ttong-gae]
Literally translating to 'poop dog', this term originally refers to a mixed-breed dog or a street mutt. When applied to people, it acts as a mild, sometimes endearing insult for someone who is acting foolish, stubborn, or a bit pathetic.
존나
[jon-na]
An extremely common Korean slang word used as an intensifier, equivalent to 'fucking', 'damn', or 'very' in English. Although it originally derived from a vulgar term for male genitalia, its literal meaning has largely faded in modern usage. It is highly prevalent among younger generations to emphasize both positive and negative situations.
꺼져
[kkeo-jyeo]
A harsh imperative form of the verb 'to be extinguished', used to tell someone to 'get lost' or 'go away'. It is a highly dismissive and aggressive command used when the speaker is annoyed or angry. Among close friends, it can sometimes be used jokingly, but it remains heavily disrespectful otherwise.
