A gesture signifying your dislike for someone or their actions; similiar to a "thumbs down" or Not!
The gesture is performed by first displaying the victim the peace sign, but then flipping it forward and down, thus inverting it.
This gesture is typically accompanied by the mimicked sound of flattulence, created using the tongue (also known as a "raspberry").
Often used on people associated with the "hippie" subculture as a form of ridicule.
"That dreadlocked fool sucks at skating. I gave him a downpeace after cheering for his lame trick."
