look up any word, like pussy:
1) An older successful and attractive male, who is dating/hooking-up with a significantly younger female

2) A male version of a cougar
Hugh Hefner is a prime example of a Stallion because he consistently dates younger females and gets lucky ;)

Male version of a cougar
Man, did you see that Stallion?

A young man who goes for an older woman. Essentially the opposite of a cougar only not as big of an age difference. A Stallion is usually with a hottie who, even though could get a guy her own age, is somehow infatuated with their younger date.
I hate going to the bar in Alberta because they let people in at 18... it's just a bunch of stallions.

Friend 1: Hey is that Jane`s stallion over there in EB Games?
Friend 2: woa he is a youngen!

Example 3

Friend 1: So i met this guy and we've been kind of seeing eachoth and I just found out he just turned 20.

Friend 2: Well your only 24... thats not that big a difference. looks like you've got yourself a stallion.

The word stallion often refers to masculine character who is known to have "good" relationship with females.

To become/be a stallion, one must first act like a stallion. Stallions often have little traits such as mastering the art of raising an eyebrow without looking like a wanker and also mastering the art of raping a girl without being caught. They are also known famously for reeling in a female using nothing but a fishing rod.

Stallions are often found in the following locations:
1. Gym
2. Workshop
3. In your girlfriend/wife/mother/sister's vagina.
Here is a typical conversation between a stallion and his betch:

Daisy: Hello
Alex: Let me fuck you under the moonlight.
Daisy: I.. I don't know what to say.
Alex: Don't say anything.. just suck my cock.

Daisy: *gags*
