This is a fun play on words. The term "Party Foul" is used when a person commits the offense of spilling a full drink. In this image the martini glass has fallen on its side and shattered against the ground. There are definitely victims from the accident, because paramedics have been called to the scene. It is unclear, though, if they are just trying to salvage the spilled Vodka or they are there to aid the injured Olives.
