-Substituting the word "please" with "plz". How difficult is it to type the extra three letters, and spell it correctly, you troglodyte, mouth breathing morons!
I feel better now.
-People who speak Spanish and all of it's sub languages and, when expressing that they are laughing, type out "jajajajajajaja", so to me it looks like some German went insane and essentially typed out "yesyyesyesyesyesyesyesyesyes".
