    I'm assuming that you have a class 'size' that contains a number of elements of which only one should be able to have the class 'checked' at any one time.

    $(".size a").click(function()
{
    if($this).hasClass('checked')
    {
        $(".size a").removeClass('checked');
        $(this).addClass('checked');
    }
    else
    {
        $(this).removeClass('checked');
    }
}

    This will do it

     $(".size a").click(function(){
    $('.size a.checked').not(this).removeClass('checked');
    $(this).toggleClass('checked');
 })

    Update

    Alternatively you could do

     $(".size").on('click','a', function(){
    $(this).toggleClass('checked').siblings().removeClass('checked');
 })

    $('.size a').on('click', function (e) {     
                    e.preventDefault();

                    $(this).removeClass("checked");
                    $(this).slideToggle();  
                 $(this).toggleClass('checked').removeClass('checked');

                });

    So late but its my answer

    $(".size").click(function(){ $('.size').removeClass('checked') //Clear all checked class on .size $(this).addClass('checked') //Add checked class to current clicked .size })

    Its cleaner,powerfull and safe.
