No I just learned British English for most of my life. I know btitish slang and sometimes I speak in a more British accent but like not a strong one obviously just a hint of British.
Like I casually say British slang cause it's what I've been normalized to.
that's not a British accent. And "not your BESt cup of tea" doesn't even work unless you're talking about an actual cup of tea or a cuppa as most British call it.
