I've been into astrology since I was in grade school (thanks to my mother) and the more I've studied it, the more I've become certain of its accuracy. People scoff and shake their heads, but I can say from personal experience that a person's zodiac sign can tell a lot about them. I've learned by interacting with Leo males that they might actually be the spawns of Satan.
Said every Leo, ever
1. They're arrogant
Technically they're described as "confident" and "sure of themselves," but I think "douchebag" is a little bit more accurate. Leo is represented by the lion, so it makes sense that they like to think of themselves as supreme beings, but they take being confident a little too far. They're unable to recognize any of their flaws and unwilling to think they ever do anything wrong. Good luck trying to ever give a Leo male constructive criticism— it won't get past his fat head.
2. They like to flirt... with everyone
Maybe it's due to their attention-whoring ways, or maybe they're just so charming they don't even realize they're doing it (I mean, I did get tricked into dating a Leo three times). You can bet your last dollar that in a room full of people, the Leo male will find someone to flirt with— whether they're in a relationship or not.
To be fair, if you have the money to pamper yourself, then there's no harm in that. But with the Leo male, he places a serious amount of importance on the cost of his wardrobe, electronic devices, shoes, etc. If you were to find any Leo male right now, he's probably wearing something designer. While this may be an attractive trait to some, if you're turned off by those that are obsessed with their material possessions and other superficial things, you might want to look elsewhere.
They're conceited so they have a hard time not making every issue about them, while their need for more and more expensive objects makes it hard for them to spend a penny on anyone but themselves. Dating a Leo male will guarantee disappointing Christmas gifts and a "K" response to your long, emotionally-charged text messages.
Being stubborn can be a good thing, but not if you're completely unable to take other people's advice. Leo males are very domineering and hate being told what to do, even if what they're being told will benefit them. Communication is key in a relationship and if your partner never wants to change their actions, habits, etc., well then...
OK, OK, so maybe I'm being a little biased in my description of the Leo male. Admittedly, all of the ones I've come into contact with have been dillholes. But my assessment is still largely backed by astrological wisdom: Leos are cocky, flirtatious, materialistic, slightly self-centered, and highly stubborn.
But they're also good-humored, affectionate, and really fun to be around. So, if you decide to torture yourself by entering into a relationship with the Lion, try to make sure he has more likable traits than douchebag ones.
