These are generally emotionally retarded kids who suffer from inadequate parenting. Since they get their asses handed to them in any competitive mode they resort to acting like douchebags in friendly free roam because it's the only way they can feel better about themselves. Unfortunately you can't teach their parents retroactively about birth control, so it's best just to boot them if you have enough people, switch to a different session with more mature players if you don't, or switch to a private free roam if you aren't having any luck ditching them.
