If i remember it correctly, according to andy and Jas, LALALI is a pun for the korean word "NALALI" which means delinquent or someone who stood by their own belief and doesn't care about what others say
LaLali is actually nalali in korean ig . It means like bad boys ( stubborn) . Them saying that, to haters they’re like bad boys who aren’t listen to them
NO, LALALI is not a real Korean word!!! It's just a wordplay rhyme for 날라리 (nallali). And it does not actually mean "bad boys" (though some could be), nor is it gender specific.
