Redefine a symbol

Question

I am writing a paper and I wish to redefine a symbol (in this case the $\Rightarrow$ symbol in latex) to read that if $X\Rightarrow Y$ then $X$ "uses" $Y$, where "uses" has meaning in the context of the problem. Is it enough to state this that I am redefining this? Is this allowed? Is there another symbol I should use?
