You could also add your own new data-attribute to your popovers as such:
$('[data-toggle="popover"][data-timeout]').on('shown.bs.popover', function() {
this_popover = $(this);
setTimeout(function () {
this_popover.popover('hide');
}, $(this).data("timeout"));
});
Now you could use
Your text
and the popover disappears after being shown the number of milliseconds you specified in data-timeout.
