Let me guess. Based on the scene from Halo Legends where Spartan 1337's fist collides with the fist of the creature he was fighting, creating a large shockwave due to the massive strength of both parties. I remember the scene in a gif being captions "epic brofist", and very similar to this.
That's fairly closed minded of you. Just because something is directed towards certain people doesn't mean only those people are allowed to like it. I'm sure even you have some interests that aren't made to your specific age or gender.
