The unexpected arrival of a family member to your home (usually on a friday night) , thus fucking up your weekend plans to get absolutely wasted/naked all weekend
Sorry darling my sisters just turned up after leaving her husband...looks like you'll have to put some clothes on and break out the chardonnay and milk tray, that's made a shagmangle of the weekend
