Educate me on Teen slang pls. Too old to understand some slangs 😆

I feel so old haha. Madalang lang ako makameet ng teenager and engage a full conversation with them. Most of my friends have senior citizen cards na 😆 and having their maintenance.. so when I meet the young ones, Ang daming youth/teen terms today na hindi ko alam ang meaning. Sometimes I have to ask the kids, what do they mean when they say...

" Eguls" "Obobs" "ASL" "Omsim" "Naur" "SKL"

And madami pa,, I just forgot the other words.

When I ask the teens, they explain it to me naman properly while I am sipping my coffee.

Ps. Not that Boomer old but yeah 😂 i need to increase my vocab. .

EDIT: Thank you so so so much for your replies! Grabe I've learned alot!! And dami na pala slangs today. Sometimes I hear it but never bothered to ask. Sometimes I google it. Now, I have to check this pag may di alam. Haha. Again, thank you kind strangers!

Thank you for being kind to your lola 😂.
