To Mr Nice Guy

Is a person who comes across as overly friendly, but in reality, they have malicious intentions—either to rob or to harm you.

You can always spot a psychopath or someone with ulterior motives when you first meet them if they come across as a bit to Mr Nice Guy.

No More Mr. Nice Guy 

A song by Alice Cooper.

And a phrase too if you want. self-explanatory...

Pretty much my new life starting today!
Fuck everyone else. I will never help another person ever again!

Also, this phrase is usually triggered by "Hooray for me and Fuck you!"

Fuck this, Fuck everybody! It's always Hooray for me and fuck you. Well thats it, No More Mr. Nice Guy!

you know what.. i'm gonna listen to that song right now!

I used to be such a sweet, sweet thing
'Til they got a hold of me.
I opened doors for little old ladies,
I helped the blind to see.
I got no friends 'cause they read the papers.
They can't be seen, with me and I'm gettin' real shot down
And I'm feeling mean.

No more Mister Nice Guy
No more Mister Clean
No more Mister Nice Guy
They say, he's sick he's obscene

I got no friends 'cause they read the papers.
They can't be seen, with me and I'm gettin' real shot down
And I'm, I'm gettin' mean.

No more Mister Nice Guy
No more Mister Clean
No more Mister Nice Guy
They say, he's sick he's obscene

My dog bit me on the leg today
My cat clawwed my eyes
Mom's been thrown out the social circle
And dad has to hide
I went to church, incognito
When everybody rose, the Reverand Smith,
He recognized me,
And punched me in the nose
He said,

No more Mister Nice Guy
No more Mister Clean
No more Mister Nice Guy
He said, you're sick, you're obscene

No more Mister Nice Guy
No more Mister Clean
No more Mister Nice Guy
He said, you're sick, you're obscene

Mr. Nice Guy 

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...

Mr. Nice Guy 

A dildo, vibrator or other masturbatory tool a woman uses while spelunking.

She goes to the market to get some things she needs: cigarettes, some chardonnay, and a ten-pack of C's for Mr. Nice Guy.

Mr. Nice Guy 

Two in the poo and One in the Goo. An opposite of the shocker.

She was bored with the shocker so I stepped it up and gave her the Mr. Nice Guy. She didn't think it was so nice!
