0919-amanda-bynes-lindsay-lohan-tmzLindsay Lohan’s NYC arrest was simply karma kicking her in the ass for tweeting bad things about Amanda Bynes ... at least that’s what Amanda is telling her friends.

We KNOW Amanda is still pissed over Lohan's tweet Monday which read, “Why did I get put in jail and a nickelodeon star has had NO punishment(s) so far?"

Bynes is griping ... Lindsay has been convicted of multiple crimes (a rap sheet as long as her IMDB page), while Amanda has been convicted of nada.

Still, Bynes is telling friends Lohan’s new legal troubles are “what she gets” for talking smack on Twitter … adding Lindsay simply is “not cool.”
