lazy dick 

the opposite of aggressive/ambitious sex; although the man's penis may be fully erect, his entire body remains in a comatose state; during intercourse the female may reach her orgasmic peak but the male very well may have been incapacitated for over an hour

Damn Brent. This chick won't stop talking about the birthday present you gave her, what did you give her? Nothing special, I think? Just some lazy dick and a milkshake, I don't remember?

Lazy dick 

When a female is in a position when her legs are spread out and her hands are supporting her body (such as she is giving birth) and the Male will sit on her with his penis inserted in her vagina and the female must move up and down very fast (humping) thus making him a lazy dick
