Angry Llama is when doing dogy style: right before you come you pull it out and spit on her back. She will think you came on her back and will turn around. Then you give her cumshot in the face.
When hitting it from behind, you spit in their face when they turn around. They will wonder what just happened, then you cum on their face & in their mouth. But to do this successfully, you MUST call your Uberahead of time.
