<?php 

// 'after_setup_theme', with 100, so it is the absolute last thing to load
add_action('after_setup_theme', 'customize_parent_includes', 100);


function customize_parent_includes() {
  //again, set this to 100 so it is the last thing loaded
  add_action('wp_enqueue_scripts', 'bootstrap_custom', 100);
}

//crap to remove
function bootstrap_custom()
{
  //-------- dequeue here! -------- 
  
  //dequeue the style:
  wp_dequeue_style('font-awesome'); //'font-awesome' was enqueued in the parent. Dequeue it.

  //dequeue the script:
  wp_dequeue_script('hover-script'); //'hover-script' was enqueued in the parent. Dequeue it.
  wp_dequeue_script('main-script'); //'main-script' was enqueued in the parent. Dequeue it.
}

@davidkryzaniak I've updated the (dequeued) enqueued file names for clarity. Feel free to change them.
