double-barreled assault and battery 

(Not to be confused with domestic violence,m since more often than not, domestic violence is single-handedly one-sided): when both partners in a relationship commit physical, mental, emotional and psychological violence and abuse against each other, usually following acrimonious arguments.

IMHO Slava Voynov's recent case is double-barreled assault and battery, not domestic violence, since both he and his girlfriend required medical attention following the incident.

double-barreled common-law assault and battery 

(not to be confused with regular, run-of-the mill domestic violence, which is strictly one spouse physically beating up the other)

when 2 common-law spouses start perpetrating physical domestic violence on each other at the same time during an argument and both require hospitalization for their injuries afterwards.

the recent case against Slava Voynov of theLos Angeles Kings is not, IMHO to be classified as domestic violence but as double-barreled common-law assault and battery, simply because both he and his girlfriend suffered significant injuries requiring hospitalization during the incident.

Slava Voynov's case is double-barreled assault and battery, not simple domestic violence, since both he and his girlfriend required medical attention following the incident.
