According to Urban Dictionary, the proper definition of a man bun is, “a questionably sexy hairstyle in which a man with hair of the medium to long variety secures said hair into a firmly rounded bun.” In other words, a rockin' hair style not many men can pull off. Loads of celebrities and popular Instagrammers have exposed the man bun and its many forms, so that the world can melt in its glory. 

Leonardo DiCaprio brings us back to his Titanic days as he searches for Rose in this extremely majestic picture. Hopefully, Rose spots his man bun and returns to her long lost love. 

He also keeps an eye out to see if he can spot any fellow man buns approaching. I'm guessing we are all jealous of that little perfect piece of hair, as we would all love to be that close to Leo.

Another celebrity, Jake Gyllenhaal, has jumped on the bandwagon with his hair sitting nicely atop his head. This bun has become a fad because of its effortless way of looking artsy and in style. An easy way to look incredibly sexy. 

Man buns are not only for looking out into the distance with a mysterious look on one's face. Oh, no, they are also for picking pumpkins and showing off the most perfect forehead we have ever seen. Harry Styles' name doesn't lie, Harry's hair has style! The voice of his bun is most likely saying, "Wow, Harry, that's a great pumpkin you've picked out! Can we carve it together later?" 

The man bun has definitely created its own fan base, but so has Instagram user, Brock O'Hurn. This Thor-lookalike can create a bun so full of wonder and delight, that it might as well have an Instagram page of its own. There is an impressive amount of volume and character to his bun, and sharing it with the world is the nicest thing he could have done for us bun lovers. 

Look at how O'Hurn is sharing the love for the man bun with future generations. Let us all fist pump to the greatest hairstyle to reach society.

And just in case you still have not had enough man bun in your life, here you go.

You are very welcome.
