Question

what is idk lolz ?

Answer 1

It's leet speak IDK is I don't know. LOLZ is laughing out loud

Answer 2

Actually, it is not leet speak. Those are acronyms that have become memes for the phrases that they represent.

Leet is a way of writing that replaces numbers and other symbols for letters in a word. For example:

|_337 = LEET
_/@9@+(_)6@ = Jagatuba

Just thought I'd clarify that. @r.arena is right about what those acronyms mean though.

Answer 3

Text lingo....
IDK= I don't know
LOLZ= laugh out loud ( the Z on the end really has no purpose other than to be cute)
