Do teens actually use emojis with “secret meanings”?

finished Adolescence yesterday and I can’t stop thinking about the emoji “meanings” from episode 2. it all just sounds like a bunch of crap?

different coloured hearts supposedly mean different things, kidney beans mean “incel” etc but i can’t find any actual sources for this stuff- all the articles are just reiterating what was said in the show

i’m in my twenties, i used emojis as a teen and i’m more than aware they can be used as dogwhistles but i just can’t find any outside sources for it. any teens/parents/teachers that can weigh in?
