Foundation default tooltips look like this:

I'd like to get rid of the small top triangle on parts of my website.
To get rid of it everywhere you just have to change the $tooltip-pip-size variable value to 0 from the foundation_and_overrides.scss file (also called _settings.scss if you're not using the foundation gem with rails).
Is it possible to define a custom version of the foundation tooltip without a pip?
EDIT
The difficulty here is that when I write something like
<span data-tooltip class="has-tip tip-bottom" title="Here are my tooltip contents!">extended information</span>
Foundation javascript generates a specific element at the end of the document containing the actual tooltip:
<span data-selector="tooltip8vxaud6lxr" class="tooltip tip-bottom" style="visibility: visible; display: none; top: 78px; bottom: auto; left: 50px; right: auto; width: auto;">Here are my tooltip contents!<span class="nub"></span></span>
You see that the tip-bottom class I added to the first span got copied to the second but that is only the case for foundation specific classes like tip-left, tip-right and so on.
What I would like to do is being able to add a "no-pip" class to the first span (the only one I actually write) and be able to alter the look of the generated span containing a "nub" element.
<span data-tooltip class="has-tip tip-bottom no-pip" title="Here are my tooltip contents!">extended information</span>
