Get a container which can go in the freezer. On paper write the name of the person you wish to freeze so that they can't do the thing you want to stop. You can use whatever convention and ritual you like for this. Put it in the container. Pour on water and put it in the freezer. Job done. (The only slight problem is a tendency for the paper to float to the top of the water and not be contained. This is easily remedied by adding more water halfway through freezing so that it's contained.)
I notice a major effect of this spell is on the magical practitioner rather than the target. As it freezes, the person or behaviour just ceases to be a problem - just exactly as if the heat has been taken out of the situation!
Oh hold on - Inexplicable likes me to post music, so here's a song which can be played while the water's freezing:
