The highly contested meaning behind this emoji means it can be used in several ways. First and foremost as an affectionate gesture; you could send the face to a loved one to express romanticism. Other love emojis could fit the bill more effectively however like the aforementioned Kissing Face.

You could use the emoji as an innocent “I didn’t do it” style of gesture. For example, your roommate comes home from work and has been raving about that last scoopful of Ben and Jerry’s in the bottom of the fridge. Once they question you where it has gone, you could respond simply with: I didn’t do it 😗
