LSMISOYNK

Modern term like LOL or ROFL, meaning:

"laughing so much I stomped on your new kitten".

A popular phrase, which definitely needed shortening to an easy to remember version like LSMISOYNK.

Person 1: I found that bloke in a public toilet, "having fun" with baked beans

Person 2: LSMISOYNK
