e-cronym
A bunch of made-up words that sound like letters, mostly used by loud, smelly, teenage girls online or in real life. They say things like 'LOL' like it's a secret code, 'LMAO' like they're telling a joke, and 'ROFL' like they’re trying to be funny but failing.
My friend texted me 'LOL' when I told her I ate a whole pizza for breakfast.
She sent me 'LMAO' after I told her my dog tried to eat my homework.
He messaged me 'ROFL' when I said my math teacher cried at my test score.
