$(function () {
    // should be in css, should use hide() function instead (faster)
    $('.spoiler').css('display', 'none');

    // new-ish good practice is to use on() instead of click(), on() allows easy event namespacing and deferring if needed
    $('.spoiler_trigger').on('click', function () {
        // cleaned up declared variables that are used only once
        var hideText = 'Hide Spoiler', showText = 'Show Spoiler',
            $this = $(this),
            newText = $this.text() === showText ? hideText : showText;

        // this animate thingy should be in, for example UI, namespace and share logic with livestreams one
        $this.next('.spoiler').stop().animate({ height:'toggle', opacity:'toggle'}, 'fast');
        $this.text(newText);
    });
