Cubing

Cubing is when you spawn a plastic cube, make it a fading door, and then open it to kill people. Mostly used alongside crossbow, being called Pussycubing. It just shows how fucking bad you are at PVP. Also cubing can be easily countered by trapping the person with another cube.

Some like to do this without the killing part, simply wanted to be left alone. Still a pussy move, it is reasonable as they aren't using it to pussybow.
