    I know the bulge is coused by the rotation of the earth, but if the earth was hit by a BIG meteor, and slowed down, whould the bulge disapear?

    If it slowed sufficinetly then the bulge would eventually disappear.

    What force would give it a different shape any way? Gravity?

    Depends on the forces of the planet's materials.

    The force caused by the rotation of the planet cause the Earth's material to bulge outwards. That force had to be powerful enough to cause the material to change from its original shape. If that force stops now, there would have to be a significant enough force acting on the Earth to cause the material to reshape. Outside of gravity, if the Earth stopped rotating, it's probably unlikely that the bulge will go away.

    The gravity will be wholly effective in removing the bulge over time. This is because the upper mantle behaves as a fluid, so that isostatic adjustments can and will occur.
