The tensity in emotions can be used to your advantage. Taking girls on an emotional rollercoaster can increase attraction btw. Make her feel happy, sad, mad, happy some more, exposed, aggravated. If you didn't do something like this, it may be why you were friendzoned. You don't want to be static and dull. You want to be round, causing her to feel all kinds emotions. (Note: You can do this without making her feel bad about herself. The goal is to tease her, but to still leave her feeling better in the end.)
I don't know too many ways to deal with disarming AMOGs (Alpha Males Of the Group). I haven't had too many problems with them, yet. Especially if you're friendzoned by her, too... Here's a few ideas.
Disarming the AMOG:
1. Becoming his friend could be useful to you. (Keep your friend's close and your enemies closer, right?)
You can do this by finding things that you both share like if he's a legit PUA, maybe even picking up women will do. You could have you a new wingman.
2. You could laugh at the girls and make them feel embarassed for being played by this AMOG, that could be enough to steer them away from him, but only you would know that.
3. You could show them how you're the better guy by learning more about attraction and breaking free from your friendzone chains. Save the bondage for the foreplay. ;P
My pick? use all 3
Attraction: If you are going to free yourself of nasty friendzone bondage, you're going to have to attract them. If you're their friend, you've already interested them, so thats some work out of the way.
1. You can keep in mind what teasing women can do to them. Remember, you are the trophy for her to win, not the other way around. So playfully teasing her on how she couldn't get you may earn you some points. If you don't think that'll work, keep in mind that making her feel various emotions will still do very good in attraction.
2. KINO KINO KINO. "Touch meh body.." Touch her, dude. Touch her every chance you get. You go and say hey to her, touch her hip for a moment, or her shoulder. Neg her with a "there's something in your hair" or " there's a smudge on your face" and touch her like you're getting rid of it. Put your arm around her and say "you're gonna be my sugar momma" or "pretend girlfriend for today." Touch releases chemicals in the brain that can actually cause sexual stimulus and usually we all like to be touched. The more you do it and better you get at it, the more she'll want you to touch her.

3. Jealousy Jealousy. If you spend a lot of time with her and she enjoys that time, take it away from her and even give it to other girls. This increases your value in her eyes because you now are more of a challenge. Hang out with other girls and talk to her a lot less. Give at least 3 days of waiting for her to talk to you before you try to talk to her again. Either way, she'll notice the change and miss the good feelings you gave her. (but this may also cause her to go the AMOG)
4. Demonstrate Value and Blow Her Mind. Show her some cool tricks that would seperate you from other guys and make you more valuable. Show your skills off, but remember, you do it mostly to entertain yourself, not her. You're the trophy and she has to prove she deserves you.
LJBFs: Just start attracting her, and you'll break free from that.
If my advice helps let me know, if you need more, holla. ^^
