Singular and plural are the same because it's a Japanese loanword. All nouns in Japanese can be used this way, to my knowledge.

I don't know what you mean lol

My mate is technically a boomer and he puts lol and emojis at the end of his messages.

My sister is nearly a boomer yet will not use lol or emojis. However she ends every sentence with at least two x's. That's every sentence!

I still don't know which is worse.

Edit: I just remembered. My mate texted me once to tell me his brother just got diagnosed with arse cancer and ended the text with a few prayer emojis, an upside down head emoji, with a lol in-between.

I've not used lol properly since we stopped using T9 keypad phones

😎 yeah you gotta add it to the beginning!

Maybe it's the psychology of inferring tone from text, and not wanting to be misunderstood in a faster-paced communications medium. A shortcut to ensure the message is received with the proper intent when the engagement time has fallen drastically?

Hard agree on this one (´･ω･`)

Oh man, I had a boss who did that. Everything else about him was amazing, but those fucking ellipses drove me up the wall.
