When someone always "ramps up" the conversation without provocation. Devrived from the game Angry Birds in which the yellow bird, when tapped will immediately double its speed at the current trajectory with total disregard to the consequences.
When the bouncer told Lawrence his party was not on the list he "yellowbirded it".

I never thought that we would get him calmed down.

Get the yellowbirded it mug.
A total indie chick. Very calm and peaced out. Doesnt really care what others think of her. Very confident in who she is. All she will listen to is indie music. A total melancholic.
Kid 1: "Oh em gee! She really loves her Indie!"
Kid 2: "Yeh shes a total Yellowbird"
Kid 1: *o_O*

The unwitting Victim of a vig. An easy con.
I left him with nothing. He was a real yellowbird.
