What does this emoji mean🙃?

[Anonymous]

I was messaging a girl on instagram and accidentally liked the message she sent (sent a heart practically) I then apologized for sending it because I didn't want to make it awkward. I proceeded to ask her a question about how far she was in to a thing that we have to do for a class and at the end she put 🙃 and I'm not exactly sure what this emoji means. Anyone know?

Sarcasm is "a sharp, bitter, or cutting expression or remark; a bitter gibe or taunt". Sarcasm may employ ambivalence, although sarcasm is not necessarily ironic

Putting up a fake smile. You think they are ok, but they aren't.

Its like, when you've given up on life. Thats the emoji. Like, you're smiling on the outside, but you just want to explode.
