The definition of "Skinny Penis" is a with ass dude on the internet saying " It's ya boi, skinny penis." That exact video made me a different person with magical powers. I can now make my penis wipe my own ass. Oh yeah almost forgot, if u watch the video 200 times your white af peepee turns black, and shrinks 40x . Best day of my life when that happened.

A guy who takes off his clothes before having sex, leaving the dick out and expects the girl to start with no foreplay. This person is usually naive and watches way too much porn. A Skinny Penis can also entail selfishness and stupidity.
