A vector points in a direction in space. A negative vector (or more precisely "the negative of a vector") simply points the opposite way.
If I drive from my home to my workplace (and then defining my positive direction in that way), then my velocity is positive if I go to work, but negative when I go homefrom work. It is all about direction seen from how I defined my positive axis.
