Lesson Vocabulary & Phrases
ばか
baka
idiot
🇯🇵 [ばか] is a common insult, but how harsh it sounds depends a lot on region and tone. In some areas it can sound almost teasing among friends, but said seriously it is still rude.
See breakdown →あほ
aho
moron
🇯🇵 [あほ] is especially common in western Japan, where it can sound softer than [ばか] in casual joking. Outside that context, it is still an insult.
See breakdown →クズ
kuzu
jerk
🇯🇵 [クズ] is a strong insult for calling someone worthless, not just mildly rude. You will hear it in arguments and media, but using it at a real person is very aggressive.
See breakdown →くそ
kuso
damn it
🇯🇵 [くそ] is often shouted at a situation, like missing a train or losing a game, not only at a person. Used that way, it works more like venting than directly insulting someone.
See breakdown →ちくしょう
chikushou
shit
🇯🇵 [ちくしょう] is an old-fashioned sounding outburst compared with [くそ], and it is often aimed at a bad situation rather than a person. You will hear it in anime, dramas, and frustrated muttering.
See breakdown →この野郎
kono yarou
you bastard
💬 [この] before an insult often means "you…" with anger, not a literal "this." You see the same pattern in [このばか] or [このやろう].
🇯🇵 [この野郎] is very confrontational and sounds like picking a fight. It is far rougher than the English gloss may suggest.
See breakdown →最低なやつ
saitei na yatsu
asshole
💬 [最低なやつ] uses [な] because [最低] is acting like a describing word before a noun: [最低な人], [最低な店]. On its own, [最低] can also be a full reaction meaning "the worst."
See breakdown →黙れ
damare
shut up
💬 [黙れ] is a command form meaning "be quiet / shut up." You will also see softer versions like [黙って] and very rough ones like [黙りやがれ].
🇯🇵 [黙れ] is blunt and hostile, not just firm. In real life it sounds much stronger than a simple request to be quiet.
See breakdown →消えろ
kiero
get lost
💬 [消えろ] is the command form of [消える] "to disappear." The same rough pattern shows up in commands like [帰れ] "go home" and [やめろ] "stop it."
🇯🇵 [消えろ] is not a normal way to tell someone to leave; it is openly hostile. It sounds like you want the person gone from your sight entirely.
