recently join social platform - snapchat [need of genz abbreviations]

hey mod lemme know which flair to put on i've no idea

so basically i find it difficult to use those abbreviations/short-forms which genz people use (obv i am also 21) but i dont know much about it.

from your perspectives list the top 10-20 abbreviations with full form/meaning here in comments or paste some document link

for better understanding heres the example - fr - for real, fs - for sure, btw - by the way, etc

hey mod let me know if i m allow to post these or if any modification needed
