Remove jQuery from previous Script with secondary script

Remove jQuery from previous Script with secondary script

Hi There, I'm working with Wordpress child themes.  My parent theme (twentythirteen) uses some jQuery to create a masonry layout in the footer and it's called in the parent themes files.  The script is below..

  2. if ( $.isFunction( $.fn.masonry ) ) {
  3. var columnWidth = body.is( '.sidebar' ) ? 228 : 245;

  5. $( '#secondary .widget-area' ).masonry( {
  6. itemSelector: '.widget',
  7. columnWidth: columnWidth,
  8. gutterWidth: 20,
  9. isRTL: body.is( '.rtl' )
  10. } );
  11. }
I want to remove this Masonry code and doing so responsbly would require me to do if from my child theme by loading my own .js which removes this action.  How can I do this with jQuery?  I was thinking that the unbind() method would be the right things, but looking more into it it does not seem so.  

i think mostly I don't know what terms to search in order to find answers on this problem. 'Remove action of jQuery selector',  'remove jQuery call'?  Etc..

Any help would be greatly appreciated.
