Colonists who are drunk (and likewise animals), may not just vomit but sometimes look for a fight. When a colonist is looking for a fight, he picks a random target in sight - a colonist or an animal. The target will be attacked if he fails a Social check. The idea is that colonists with high Social can talk their way out of trouble, and colonists with low Social are those the drunk is likely to have grudges against.
+ Social, one of the most important skills in the world, becomes more important in Rimworld.
+ More opportunities to train Social
+ It becomes important to have decent Social not just on a single colonist who does all the talking, but on everyone. Colonists who have decent Social get along better.
+ more emergence. Especially combined with Animal Solidarity idea I posted in the animal thread.

Interesting idea... with the prospect of relationships and in-depth social interactions coming in the near future, maybe even Alpha 13 as Tynan said in his reply to this post: https://ludeon.com/forums/index.php?topic=14969.msg161825#msg161825 , the relationship of the drunk with other colonists could impact, i.e he is friends with one colonist, but is the sworn nemesis of another, who would he attack? Also, whoever he does attack would take a severe relationship loss towards him. The idea of talking someone out of it is good in writing, but would realistically be a bit too in-depth.
Why too in-depth ? It could work similar to animal taming or colonist recruiting.
One colonist approaches another colonist. A speech bubble appears a few times. Finally, if the result modified by Social skill of the victim is too low, the fight starts.
I wasn't thinking of it that way, but I guess it could work.
