In Responsive Design, how do you trigger Tooltips? mouse hover isn’t there anymore

A tiny disclaimer, not looking for tooltip alternative for mobile as in another UI Pattern, i'm looking for a different interaction that could trigger the tooltip, i hope this makes it clear.

The Question

There are many ui patterns that rely the hover event/selector, some patterns are informative some are interactive.

With mobile phones/tablets the hover effect is non-existing - so far at least ? - are there any techniques/tactics that can be used to tackle or workaround this problem?

Tooltips are a good example:

Before Answering

While you can, please avoid mobile-first sort of answers, as much as we like to stick to the bible of design, we know that in reality there are many cases out there that simply can't go mobile-first, could be that it's not a priority or simply adding the mobile aspect to an existing web design.
