Show unblockable popup with desired content

Is it possible to hide a content in the post and only show it when someone clicked on it? I tried to search for unblockable popup plugins but most of them require you to add the popup content on a separate table on the database. All I want is just a shortcode for example below

[popuptitle=My Office]
My Office address
[/popuptitle]

So when someone clicked on My Office on my post, it will show up an unblockable popup with the content My Office Address.

Thanks in advance! ??
