:u Edit Meaning

1.

A parody of other emoticons.

Like people who abuse "LOL" "XD" and other emoticons/abbreviations, :u serves absolutely no purpose. In fact, it merely takes up space. Abuse it wisely.

"hai guyz i would <3 to meet you lol XD XD "

"Get off my internets, pedo. :u

2.

The face somebody makes when they charge their laser or get read to do a light beam attack through their mouths.
