When a random girl is giving you a blow job pull out your dick right before you cum, spill chocolate powder in her face and proceed to ejaculate. After performing this move the girl is gonna be stunned for a couple of minutes, so you can easily escape the scene. This is used when you realize that the girl blowing you either has a dick, or is ugly as fuck.
guy1: dude are u ok? I saw you running out of the hotel last night.
guy2: Yeah, I realized that the girl blowing me had a fuckin' Penis! But everything is fine, I performed a Chocolate Milkshake and escaped with mi ass untouched.
