What even is curly hair anymore?

i’m not looking to start an argument i’m just genuinely confused at this point. i have 3b hair and my social media feed is filled with girls with 1b or 3a hair. all my life i figured my hair was curly but i was recently told i don’t have curls, i have coils because the mixed girls with loose curls is already considered curly so like what does that leave me?? also what is forced curls? i thought it meant those who had to apply product and physically go through each strand of hair doing a finger curl or wtv but others argue otherwise

again not looking for an argument, but your insight would be nice
