Short for ‘Laughing my sperm/spunk out’. Used in cases where you’d use LMAO.
It’s like Lmao but just for the lads. Especially for the lads that don’t wanna be seen as like “feminine” or some shit for using it.
A varient of it could be LMFSO, meaning ‘Laughing my fucking sperm/spunk out’.
Can also be used in past tense, “Laughed my sperm/spunk out”.
Can also mean the child-friendly version of lmao: Laughing my socks off
Tom: Haha, Lmso

"Laughing My Shit Out" Used as an alternative of LMAO (Laughing My Ass Off). When You laugh so hard that feces shoot out of your ass.

Get the LMSOmug. LMSO means laughing my shit off. Instead of saying laughing my ass off (Lmao) you use lmso instead if you are laughing a lot harder.
