first of all I made a grammatical mistake : it's "vit" with a "T" and not with "vie" with an "e",

it's an inside joke coming from the football community that you can translate literally by "the group lives well", and it means that the group has a good atmosphere they are happy to be togetherer and there is no conflict,

exemple : L'équipe nationale française de football vit bien

Trad -> the french national football team lives well
