There are several so I'll put them at the top in a short list then elaborate below.
Whiners
Lack of Confidence + 'Friends'
White Knights
High Aimers *
Uncreative Knobs

Whiners. I hate men who whine about something that they either can't control or won't make an effort to change. If something is actually bothering you then make an effort to change whatever it is, or learn to deal with it just like everyone else. Or whining about political movements and stuff. Yeah feminazis are shit, as a submissive I deal with them too because I'm 'setting back the gender' or whatever. They're cunts, but you don't need to whine about them to everyone who will listen. It's annoying.
A lack of confidence and (an extension of whining) the concept of the 'friend zone'. If you want to fuck your friend ask her on a date, don't go over to her house and give her a pedicure. Pining is gross and makes a girl's panties drier than a desert. The flip side is that if you're confident enough to walk up ask straight-out ask a girl on a date, chances are you'll be much more successful.
Really, just own whatever you are, or change whatever you don't like. You're a fat guy? I don't care, but it's whether or not you do. If you own it you're much sexier than a lot of guys out there. And if you don't like it then change it. You don't -need- to be muscular to get a pretty girl, you just need to be confident and, if you want to keep her around for a while, a decent person.
On that note: Don't be a fucking White Knight. Holy shit, nothing is more pathetic. Just stop. If you want to be a feminist that's great, but don't shove it in my face and try to make me 'feel better about being a woman' and showing 'how much you're trying to uplift my gender'. I'll need a lobotomy before I sleep with a guy like that.
Everybody wants to sleep with someone good looking, and people rarely want to sleep with 'ugly' people. We're biologically predisposed to be that way. And by all means, aim high, if you're a solid 5 and you're at the club, shoot for that 10 if you want*. You might even get her. But for the love of fuck don't be mad if she says no. She's not required to sleep with you if you bought her a drink, and if you did that of your own free will you have no right to call her a cunt. However, if she says "How about you buy me a drink" then curves you, yeah, she deserves that.
* It's not the fact that you're aiming high that I find annoying, actually I kind of like it because it shows confidence. What I don't like is when you call me a name because I shot you down and then spend the rest of the night stalking me. THAT is the annoying part. (Also, I'm in no way saying that I'm a 10, I'm probably a 6-7, but the concept is what matters)
Finally, the unimaginative. If you're messaging someone on Tinder or a dating site, or even on here, don't just go "hey". If you do that I'm already done with you. Say something substantial, something to latch onto that shows you're more than just another strand of "hey" in the pile. Seriously, do you have ANY idea how many messages and shit a girl gets? If you're not going to make yourself stand out, I'll just move on and swipe right on the next guy.
Edit: Holy fuck, that was a book. I'm so sorry, I get a bit wordy sometimes...
