'xoxo' is acronym means hugs and kisses. 'x' is symbol for kissing. 'o' is symbol for hugging.

hm what about OXXXXXXXXXXXXXXXXXXX than unhug

It's a girly way of ending a letter. I have no idea why it means kisses and hugs though.

That is very interesting- can you guys explain why X means kisses and O- hugs? :)

hugs and smooches
