The actual meaning of おっさん臭い


I think おっさん臭い literally means 'old man stench', if I'm not mistaken, but it
seems like the actual meaning is different.

For example, in this episode of ちびまる子ちゃん Tomo says

> "なんかちょっとおっさん臭い気がするけど"

after (if my listening comprehension is correct) a classmate with a weirdly
formal style of speech tells her that doing certain eye exercises will open up
a 3rd eye that can predict the future.

And then in the show 推しの子 at the end of episode 1 at timestamp
1:19:13(spoilers for episode 1)

> Aqua, the brother says:

> > "スカート短すぎないか？"

> To which his sister Ruby replies :

> > "お兄ちゃんって昔からおっさん臭いよね"

Is おっさん臭い used to mean 'creepy', 'weirdo', or does it have some other
meaning(s)




The suffix くさい makes up i-adjective meaning "have similar
appearance/behavior/though/vibe to..." with a negative connotation, as well as
physically "have bad smell of..."

おっさんくさい can be used in both ways, but in the context of 推しの子, Ruby states that
Aqua have behavior/thought similar to that of old men for long.
