can you give me the link to video or source?
As far as i am known to theoretical negative mass it will have opposite effects of gravity unlike attracting it will repeal. And due to repulsion caused by gravity every thing (even the matter on the tip of the universe) will repeal due to law of newton stating gravity acting by a body on a body is never 0 (like gravity on earth acts on all matter in the universe) so the universe as a whole will try to move away from the body in all directions which breaks law of conservation of energey (here momentum). This is just one of law but negative mass breaks all laws of physics; so its called exotic matter. For this reason its not possible(for now?) and only a thing on paper.
Think of it like particles breaking not one but all laws of physics and making einstein go NUTS and driven him crazy enough to destroy the particle from the existence before it came. So the particles have to pretend to follow all laws for now (dont know about future suppose a mad man kills Einstein from existence and becomes the law keeper and makes us go nuts Jk).

Well, if anything it's hypothetical and has never been shown to exist. But indeed, physics predicts some weird behaviour (as far as I know) for negative masses, should they exist. Here's a video about hypothetical negative masses:
