1. Like a male peacock uses his feathers to attract a mate, peacocking involves using a man's clothing and adapting his behavior in an over the top and flashy manner, for the purpose of attracting women -- but not necessarily a mate.
Notes About Peacocking
Peacocking isn't just about being outlandish or outrageous, its about attracting attention in an appropriate manner for both individuals (the one(s) you are trying to attract and yourself) as well as for the venue (i.e. a coffee shop vs. a bar). Therefore, if wearing lots of flashy jewelry or having piercings all over your face doesn't jive with your personality, it probably won't fly. The key is to use props and accessories in a way that mirrors who you are -- but amped up in order to stand out from the crowd.
