it stands for fuck it smile, a lifestyle created by Jay Anthony of the Diligentz, a Bay Area hip-hop group
"Well the abbreviation F.I.S can stand for multiple sayings such as; Fuck It Smile, Forget It Smile, Forever I'll Smile etc. The whole point of this brand new movement is to show people its okay to smile and its okay to be yourself.Life is way too short to trip off all this bullshit thats been going on, and i feel if you dont live by the rules of F.I.S life is going to be damn near too hard to accept.
MORAL: F.I.S..FUCK ALL THE BULLSHIT..DONT GIVE INTO IT..JUST SMILE AND MOVE ON...im not saying be a bitch, but some things just arent worth the trouble."-Jay-Ant
i'm livin that F.I.S. lifestyle, fuck all that bullshit, i'm just gonna make sure i'm happy.
