Which one is X or O?
The Internet abounds with origin theories. There are visual explanations: that “x” resembles a kiss, for example; that “o” looks like an embrace or the union of bodies; and that “x” and “o” together form a kiss on a face.
What's X and what's O?
One alternate theory that has gained a little traction over the years, is that the above theories on the “X” and “O's” are all wrong and it is the X that means hugs, mimicking two people embracing, and the O that appears to be a mouth puckered for a kiss, hence why it's “hugs and kisses”.
