Lol (said L-O-L or lol) is the short Version of Laughing Out Loud. People often use lel or lul, but that is completly wrong. It's used for someone who has no Humor or for texts. So please explain it to your mother Gary...
Gary looks up to his phone. His Ma is calling.
Mother: Your aunt just passed away. LOL. She will be greatly missed.
Gary: WTF Mom??? Why is it funny???
Mother: It's not funny Gary, what do you mean?
Gary: Mom, LOL means laughing out loud...
Mother: Oh no! I thought it meant Lots Of Love! I gotta call everyone back!
Gary: Not again...
