Stands for 'Dump
The Motherfucker Already'. From
Dan Savage's 'Savage Love' column. It's advice given to someone complaining about a significant other's repellent behaviour. Often given, seldom taken. Concise, if not tactful, it's often a shock to the complainant, who might not be able to look at the situation objectivelly and see how bad it's gotten.
Should be used either when a person keeps repeating the same complaints over and over again and seems unhappy in the relationship and unwilling to do anything about it, or when anyone can see
at a glance that it's a toxic, if not abusive, relationship.
