look up any word, like fleek:
 
7.
A phrase used by single men to explain their single status, usually in conversation with women, or in a personal ad. Often uttered in a whiny tone. (Actual niceness of the single man is largely irrelevant when using the term.)
When Julia turned him down for sex, Julio further justified her decision when he whined, "Nice guys finish last!"

It basically means that you will never have any sex whatsoever in your life if you don't treat women like shit.
The polite and well-mannered man who treated women like royalty realized too late that nice guys finish last.

The idea that if you are nice to a girl, compliment her, tell her how amazing she is everyday, and really just genuinely show her how incredible she is everyday, that you will never get her to love you. Sadly, this is more than true in most cases. You know when you love this girl, and you're always there for her no matter what, and she always goes for the assholes that cheat on every girl they date and treat them like shit? Yea, thats cause your the nice guy. However, there is nothing wrong with you at all, and the truth is that it is her loss.

Why do nice guys always finish last? Because they put their girlfriend first..
Colin: Hey man, why wont she date you instead of going off with some other douche who never pays attention to her!

Kyle: I dont know man, just proof that nice guys finish last.

Can be a double entendre as it can refer to other meanings as well as the fact that a nice guy will let a woman have an orgasm(s) first thus "finishing" last. This is different from a man who's only concerned with getting themselves off and when they finish first, the women then often doesnt get to finish at all.
"So how was it last night with Joe?"
"Not good he got himself off and was done before i had an orgasm"
"What a jerk, guess he doesnt know, nice guys finish last"

4.
A phrase that references the general lack of incentive/respect that is provided by society for virtuous behavior, instead being reserved for those demonstrating more superficial qualities.

In the material sense, this is all too often true in that the price of success is forgoing one's integrity to satisfy a culture based largely on insincerity and self interest.

Philosophically, the benefit of this lifestyle is debatable.
1. Boy did you ever bomb that interview by not laughing at the recruiter's dead baby joke. Nice guys finish last, fool!

2. Nice guys finish last...but nly if you're racing the wrong way.

A saying that means if your mean to chicks (amongst other things) you'll get ahead rather than if your nice all the time.
If nice guys finish last then sweet guys have 4 tires blow out of the second turn and explode on the 3rd.

an awesome green day song that is true punk in nature; the premise of the song (probably the most truthful thing I ever heard) is that just because your a nice guy and treat the women great, doesnt (usually) means you wont get anything in return (since women only care about money/looks/power)
Oh, nice guys finish last,
When you are the outcast,
Don't pat youself on the back,
You might break your spine
