LFR; pronounced (Liffer); is an acronym thats stands for Lick, Fuck and Rub. It is can be used when talking about what a female does to a male during sexual intercourse
Collin: Shut up Ed I fucked your mom Edwin: Oh yeah Col? Is that why your mom gave me LFR
We all use lol in normal texting but we never actually laugh out loud in real life. LFR mean Laughed for real or laughing for reals. Meaning actually laughed when we typed what ever was said.
