Cobra Dick 

When the head of the penis while erected is bent downward so that it resembles a Cobra head when ready to strike.

Look at Carlos' cobra dick. It looks like a damn cobras head with the way it's bent!

Cobra Dick 

A penis that has been caught in A Zip and has split the foreskin. When a woman gently blows (blows air)the forskin opens like a Cobra when about to attack.

As Toby ran naked down the street, his cobra dick was flapping every where.
