I learned about emojis awhile ago and have been using them. I googled and found much of a muchness.
What I have discovered - if I make a sad face and look in the mirror – I see what looks like an emoji – downturned mouth (but to get the edges really to go down I have to get my lips to make an upside down U ) which means my chin comes out and I look pugnacious.
Now I have been telling a friend or two what I am doing and am trying the expressions on them. The results have been rather startling. As I was trying to look sad and then started to rub my forehead one friend asked me why I was doing that and I said because you are trying to look sad too and your forehead gets all wrinkly so I was wondering if mine did too. That made us both laugh. LOL That I understand.
Then I wondered what other Large Caps like LOL. TTFN. SOS. BBF. NNTR. mean so I googled.
IYKYK. came up. (If You Know You Know) Well. NIK. (Now I Know)
