What could コエーぞ mean in this context?


Hello im reading a comic where a girl is trying to get a guy to come to
school, the guy brushes it off and replies 俺はコエーぞさっさと帰れ. From intuition, im
getting the vibe of "Don't bother ( Ill pass), go home/ get lost" But what
exactly does コエーぞ mean here. 怖い or かわいそう come to mind.

Thanks




I could well be wrong, but this parses out to me as slangy / informal for
怖【こわ】いぞ, i.e. "I'm scary / that's scary".

The _-ai_ or _-oi_ endings on various adjectives often collapse to _-ē_ in
informal speech, such as _sugoi_ → _sugē_ , _shiranai_ → _shiranē_ , and here,
_kowai_ → _koē_ (since there isn't any _we_ in modern Japanese).
