A shit so long and solid, the head of the turd sticks out of the toliet bowl water; resembling that of a deadly cobra. The deuce cobra is considered extremely dangerous and should not be provoked, if your roomate or wife leaves a deuce cobra for you to discover, you need to remain calm; the cobra is more scared of you than you are of it. However, it may jump out and spray your face with doody. If your wife left it, than she is a high fiber diet whore.
Nigel thought it would be hilarious to leave Ty a deuce cobra after he ate a bunch of raisin bran drunk...until he came home and found his roomate dead in the bathroom and a shit streak from the corpse to the fire escape where the deuce cobra made its exit.
