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.

🤪

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.

🖕

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.

😤

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.

💩

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.

🤬

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.

🫏

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."

🤫

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.

🚪

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.

What Learners Are Saying

Teaching in Osaka and I wanted to connect with my students beyond the classroom. The everyday conversation scenarios made my Japanese feel natural, not textbook-y.

Mia S., 25, English Teacher

Moved to Tokyo and the polite vs. casual speech levels were killing me. This app breaks it all down with real scenarios. My coworkers noticed the difference in weeks.

Kevin Z., 31, Game Developer

I tried five different apps before this one. The roleplay conversations are what finally made things click. I actually remember what I learn now.
