You can try your best to interpret the acronym KMSL all on your own, but it's such an obscure one that you'd probably have a pretty hard time with it.

KMSL stands for:

Killing Myself Laughing.

Confused? You have the right to be!

This acronym tricks you into thinking there are four words in it when really there are only three. Whoever coined the acronym must have thought that the word "myself" was actually two separate words (my self) because that's what the acronym seems to imply.

The Meaning of KMSL

A variation of LOL, KMSL is a parody acronym meant to be used when a person really wants to convey and exaggerate their amused reaction during a text-based conversation. These days, less common variations of LOL like KMSL can be more effective at expressing amusement in a world where LOL has been so overused that it's lost much its meaning.

Even though no one ever literally kills themselves with laughter, they can use KMSL to show just how much something seems funny to them. Whoever's on the receiving end of the KMSL reaction will probably get the hint that the person reacting is extremely amused and thus reacting in a very amused way behind their screen.

Examples of KMSL in Use

Example 1

Friend #1: "Got dressed too fast this morning and didn't even realize there was a pair of underwear stuck to my pants until I got to class..."

Friend #2: "Kmsl!!!"

In the first example above, you can see how Friend #2 uses KMSL as a standalone reaction to Friend #1's message. In many cases, nothing more is needed than the use of the acronym all by itself.

Example 2

Friend #1: "Did you watch last night'e episode of the big bang theory?"

Friend #2: "Yeah I was kmsl the whole time... such a funny show!!"

In the second example above, Friend #2 uses KMSL in a sentence to describe a reaction they had in the past. It can also be used in present and future tenses (such as "I'm kmsl" and "I'll be kmsl").


The exact interpretation for KMSL (Killing Myself Laughing) is sometimes used interchangeably with the acronym KML because KML does away with the extra letter that's really unnecessary for the word Myself. In other words, you could use KMSL or KML and it could be interpreted the same.

Unfortunately, KML does have another interpretation, which could be one reason to stick with KMSL. Some people interpret KML as Kill My Life, which has a similar interpretation to FML (F*** My Life). 

Alternatives to KMSL

KMSL is one of those acronyms that's part of a larger group of creative and exaggerated variations of LOL. Here are just three others that you can interchange with KMSL.

PMSL: Pissing Myself Laughing. Very similar to KMSL, but perhaps just a little more inappropriate. At least it doesn't include an F-bomb.

ROFL: Rolling On The Floor Laughing. More popular than KMSL and PMSL, ROFL is a good one to go with if you want to stick with acronyms that are more recognizable. 

LMAO: Laughing My Ass Off. A very well-known variation of LOL, perhaps even more than ROFL.
