If you happen to be in possession of a large apple you tell
people to "
lick your fat apple".
Fat apples from the grocery are very lickable and a great treat to share with your friends, so if you own a fat apple simply say LMFA and all your friends will love you.
Bradi: Ugh that Maya girl... I hate her, she keeps talking about this guy Nick and doing nothing about it.
Jack: IKR?!
Maya (from the distance): LMFA
Bradi: OH MY GOD REALLY?! I LOVE HER
Jack: HOW DID SHE GET A FAT APPLE????
THATS MY BEST
FRIEND NOW
