微妙

Not great

💬 [微妙] often means more than just "not great" — it can be a soft, indirect way to say something is awkward, questionable, or not really a yes. You'll hear it as a polite-ish dodge: [それは微妙] = "that's... kind of iffy."

神

kami

Amazing

🇯🇵 Calling something [神] is strong casual praise, like saying it's god-tier. It's common in speech and online, but too slangy for formal situations.

チキる

chikiru

Chicken out

💬 [チキる] is slang built from [チキン] and [る], a common way slang turns nouns into casual verbs. You'll see the same pattern in words like [ググる] for "google it."

ノリノリ

norinori

In high spirits

💬 Repeating a word like this often adds a sense of being full of that feeling. So [ノリノリ] is not just "in the mood" but more like really into it, full of energy.
