Lmso 

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

Lad 1: Did you see Brooklyn Nine-Nine last night?

Lad 2: Yeah, Lmso!

Lad 1: Same dude!

When your shit is so stubborn that you have to laugh to get your annoying shit out. lmso stands for: laughing my shit out. It is the more prestige version of lmao. And no, it doesn't work for birthing.

I was so constipated that I had to consult to a cumless child and a communist thot to lmso.
