Lshmafo. Means Laffed so hard my arse fell off. Used when people type something that they find reely funny but no one else does. Mostly used in sarcastic circum stances
Ellie: Omg it was so funny on the bus today jack drew a willy on the window cause it was all steamy *falls about laughing to self*
Jodie: lshmafo *thinks... wow that reely wasnt funny*
