If four-person teams are in use, then 4BBB works like this: All four golfers tee off and play their own balls into the hole. The low score among the four counts as the team score for that hole. When 4-person teams are in use, 4BBB is played as stroke play.
If two-person teams are in use, then Team 1 and Team 2 tee off together (so four balls are still in play), and each team's low ball counts as that team's score on each hole. With 2-person teams, 4BBB can be played as stroke play or match play.
Another way of putting it: 4BBB is just another name for a best ball (4-person teams) or better ball (2-person teams) format.
