Mr. Nice Guy, Is a way to describe the certain situation -Where your dick is not HARD, nor Soft.... Meaning there's enough blood pumped in it to give it some respected amounts of girth and heftiness, and a very nice banana shape... And, there's not enough blood to make it erect and create some discomfort in public nudity places(i.e Public showers, Schools gym shower, Sauna...).
All this makes a perfect situation for walking proudly among other fellow men which do not or are not currently having this phenomenon.
Public showers are a great place to have a "Mr. Nice Guy", because you walk proudly among other shrinked and springie looking dicks...
Also a great time for it, is when you show him to a lady, So she can fully appreciate the shape and size of the tool.
Guy A, *Walks into the showers in his health club... While having a "Mr. Nice Guy"...*

Guy B Through F, Look(or rather glance, to not seem homo/gay) with awe and respect to Guy A's penis to see the marvel that walks among them...

***Needless to say -Guy A walks tall and proud of the 7th wonder of the world hanging astonishingly from his lower body...

The pattern of behavior in which a man slowly forfeits his masculinity to a woman believing that by empowering her, he is proving his love for her. This eventually creates a parasitic relationship in which the woman takes everything the guy does for granted and ultimately breaks his heart, leaving him an empty shell without the motivation to start over- the whole time never realizing why this keeps happening to him.
"I don't understand what I did to deserve this"

"You just suffer from the nice-guy complex"

Get the nice guy nick mug.
A typical saying by guys who's not generally nice. They're simply saying this thinking the girls will have sex with them if they say this phrase. They generally say this over and over to a girl, so she thinks he's a nice guy, but once she rejects him his true colors come to the surface.
Fake Nice Guy: "I'm such a nice guy. Why won't these bitches have sex with me?"
An Actual Nice Guy: "Girls won't have sex with you, because you're a total douchebag."
Fake Nice Guy: "Whatever asshole, I am a nice guy. Girls are just total bitches!"
An Actual Nice Guy: "Whatever helps you sleep at night."
