Hi5 is a social networking website aimed at people interested in flirting, dating and making new friends. It is almost identical to the Tagged website. Both sites are owned by social and mobile tech company The Meet Group.

You may not have heard of the social network Hi5, but it's been around longer than Facebook, Instagram, Snapchat, Tumblr and Pinterest and it's still popular.

Hi5 became one of the most popular social networks in 2007 when it experienced a huge growth spurt, much of it from Central America. The site got its name from a feature that allowed members to give their friends virtual high-fives.

Fives were used to describe a friendly relationship. There was a time when users could give warrior fives, crush fives, teammate fives, swank fives and many other types of fives.
