National Selfie Day is June 21. In honor of the holiday, here is a list of the most popular selfies we see scrolling through our timelines:

After a night out—or in—a squad must take the necessary group selfie. Ellen's 2014 Oscars selfie is one of the more famous groupies, which was worth nearly $1 billion in advertising.

The gym selfie

After a grueling workout, there’s no more reasonable way to cool down than to take a sweaty selfie. These are becoming increasingly more common on Snapchat, following a workout tutorial.
