A form of gang initiation commonly used in Brownsville, Brooklyn, and sometimes seen in East New York. Initiates will, sometimes unknowingly, smoke a blunt filled with a mixture of marijuana, PCP, and salvia. This creates a series of intense hallucinations, and often times users report feelings of being totally removed from reality. It is such an intense experience that initiates can experience psychological difficulties after coming down from the trip including anxiety, PTSD, and even psychosis. After the villy has worn off, the initiate is held down and a mark is either tattooed or engraved into their face, typically under the left eye. The mark given depends on the initiating group, the most common being three dots in a triangle formation given by Crip sets. Others include V's, A's, and block triangles in the same area.

The use of this initiation is relatively recent and very dangerous. It should not be attempted by anyone, as overdoses can easily occur.

The name is obviously derived from the combination of "Ville" and "Philly", a common brand of blunt wrap.
