why does Nick talk thru his teeth?

That "bashful" head tilt and mumbling super-fast "talk through his teeth" thing is infuriating. Clearly it works with the ladies, but some of his tics like that seem like fallback "nice guy" mannerisms when he's actually being very passive-aggressive. He'll deliver a rather blunt or cavalier or dismissive response but bury under that effeminate head shake and bashful eyes and fake-shy demeanor.

It's also becoming incredibly clear why the guys on previous seasons didn't like him. Not that Shawn Booth or Josh Murray and many of the guys from those seasons aren't mega-tools in their own right, but you can see how Nick's cavalier, dandy-ish fake-good-guy routine would rub other guys the wrong way. He seems very much like one of those guys who has a hard time making male friends but ALWAYS has to be in a relationship or surrounded by women flattering his ego.
