migas is a platform created by Buzzfeed to talk about anything surrounding women and female universe, such as empowerment, useful informations and fun. The page used to be called "Pink" but they wanted to go away from the stereotypical image of being a women. "migas" means "girlfriends, sis" in Portuguese and it is a famous slang for calling your best friend.
The main idea of migas branding is to show the sorority and sisterhood between women. One supporting the other thru the internet, in person or by soul.
Giving a high five is like supporting someone you like, greeting them for something especial. Giving the special support every friend needs.
