A dialect of the English language used by teenagers (normally between the ages of 13 and 18, though there has recently been a leap in speakers).
This form of speech includes an overuse of words such as "like" and "umm". There is debate over whether small words such as "what" and "so" should be added, but as for now it is only the two previous words that can be easily linked to this dialect.
God, that kid needs to learn that teenspeak and English are NOT the same language. I mean, he's always going, "Like, I heard that, like, there's gonna be a party on, like, the umm... the 24th."
