Alright x-D

$(".Clicked").trigger("click")

You can rewrite your trigger like this:

$('.LikePost').on('click', function(){

// just invert classes state
$(this).toggleClass("default");
$(this).toggleClass("Clicked");

// if is default, its liked, if not, its not liked
if($(this).hasClass("default")) {
    alert("post liked");
} else {
    alert("post unliked");
}
});

And if you want to manually trigger all liked posts, just do it:

$('.Clicked').trigger('click');
