"Fam" can refer to someone's family. On a forum, FAM can mean Fake-Ass Mod or FAMing/FAM'ing can mean Fake-Ass-Modding and refers to a member who isn't a moderator but tells other members off and acts like they have authority.

Your subscribers on youtube that are so litty that England is their city. They also love the Emoji Movie as much as Patrick Stewart did. They do make fun of your forehead though, which isn't always the best thing.

The fandom for 5 Seconds Of Summer. Short for 5SOS Family because we are not a fandom but a family. Everyone is loving to eachother. The boys of the band are Micheal Clifford, Luke Hemmings (lucas), Ashton Irwin, and Calum Hood all love the 5sos Fam. Easily the best fandom you can be in. It's a beautiful place with pizza,kittens,puppies,rainbows,and band merch. But at the end of the day Jack Hemmings slays the game.
