It means 20 items or units, the X's on Roman symbol for number each x equal 10 so if their's 3 x's then it would be 30.

Or if their doing X.X then that means their annoyed or irritated.

xx just means two kisses, x means one kiss, xoxo means kiss hug kiss hug. Hope I helped!

Everyone on twitter is referring to the band 'the xx'. Somehow that band has managed to write a song relating to every subject in the world, and that is what people mean when they write xx.

Xx means the sign of sexy.
