The equivalent to 'extreme wow'. The real X3O3 is done by crossing your arms, putting your hands up to your mouth, and holding up three fingers while having your mouth open. If you are talking to someone through text you simply put X3O3. This shows that you are doing the hand motion but you cannot show them.
Billy: I am the coolest person ever.
Taylor: X3O3, you're a faggot.
