Another name for the male penis. Usually only used if the penis is a talented one that can inflick massive pleasure for the sexual partner at that time. Someone can call their penis "Doink" only if they have never had even a medial compliment. it must be amazing!
Hey baby!! dont bite to hard on the doink!

Don't make me come overthere and throw some Doink down!

It's FREEZING outside and my Doink aint a bit shriviled!

Imma smack that hoe in the forehead with my Doink!

She took all but three fingers of my doink down her throat!
