Here's the context:

I searched in jisho.org for **ぶっこ** or **ぶっこく** (cause of the いて conjugation
for く-ending verbs) but they don't match, I hope the context is clear enough.




ぶっこく is a slangy, colloquial and vulgar verb used in place of 言う, する, でいる etc.
It has a contemptuous or mocking nuance, although it's not as offensive as
ほざく/ぬかす. Look up ぶっ and こく separately for the etymology. 都会風ぶっこく in this
context roughly means "to behave/speak like a city girl", but it sounds more
slangy than this.

For some reason, ぶっこく is often used with 余裕. 余裕(を)ぶっこく means the same thing as
[余裕をかます](https://jisho.org/word/%E4%BD%99%E8%A3%95%E3%82%92%E3%81%8B%E3%81%BE%E3%81%99),
and it may be memorized as a slangy set expression.
