LMK slang meaning on Snapchat

Someone was having a chat with me on Snapchat and said LMK. I wondered, what the heck does LMK mean?

Upon asking the sender, she revealed that LMK is a short form for Let me know.

I was surprised that people started using acronyms for such easy words nowadays. I had an argument with her about this and we discussed this further saying that it can also be used as Lend Me Knowledge or maybe something more than that. She convinced me that it doesn’t work like that, and such social media slang words have been validated by users all over the globe.

So, here it is, now you know that LMK is used for Let Me Know on Snapchat, Instagram, WhatsApp, and often Facebook.
