You need to import jQuery first. Place your code inside a method like .ready or .click that will trigger the event.
jQuery(document).ready(function(){
jQuery('#load').text(function() {
jQuery(this).text('MÉG TÖBB MEMORABILIA');
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="memorabilia">
<button class="btn btn-primary" id="load">More Memorabilia</button>
</div>
EDIT:
You can ommit the second line. So the final code will be
jQuery(document).ready(function(){
jQuery('#load').text('MÉG TÖBB MEMORABILIA');
});
