2. めちゃ (Mecha)

A Kansai dialect term that has spread throughout Japan, “mecha” is an intensifier similar to “very” or “super” in English.

Borrowed from English, “nau” is short for “now” and is often used in social media posts to share what the user is currently doing.

5. げんき (Genki)

Although not technically slang, “genki” is a colloquial term used to ask how someone is or to encourage someone to cheer up. It’s equivalent to “are you okay?” or “cheer up!” in English.

6. ばか (Baka)

This term is akin to calling someone “idiot” or “fool” in English. While it’s used between close friends in a light-hearted manner, be careful as it can be offensive if used inappropriately.

“Yabai” is an incredibly versatile slang term. It can mean anything from “amazing” to “terrible,” depending on the context and tone of the conversation.

8. ちょっと (Chotto)

“Chotto” is a casual way to say “a little” or “a bit.” It is also used to politely refuse an offer or to show hesitation.

9. わかる (Wakaru)
