look up any word, like dirty sanchez:
 
1.
The act of taking a man's penis inside one's mouth and blowing a 'raspberry', or humming, whilst said penis is inside one's mouth. The aim of this is to send orgasmic vibrations down the shaft of the penis in order to give the receptor the best jizz of his life.
My girlfriend gave me a shaft raspberry last night, there was cum everywhere. It sounded gross, though.
