F4F

An abbreviation for "first for first," a common comment on popular social media posts that promotes the exchange of "likes," in which one requests a "like" on the first picture on one's own page in return for liking the first picture on the other person's page. Ever since I started writing "F4F" on famous people's posts, my Instagram pictures have been getting way more likes!
