Kristen Bell tried not to laugh while Dax explained the middle finger to their daughter.

Explaining cuss words, their implications, and why we shouldn't use them in our daily interactions can be a complicated conversation to have with your children - particularly if you swear yourself.

However, with the stream of swear-filled media and the influences of other children, giving your children the low-down on cuss words is an inevitable conversation. It's not a matter of whether it'll happen, but rather, how your household chooses to handle it.

For Dax Shepard and Kristen Bell, parenting their daughters Delta and Lincoln is all about transparency and finding the fun in all the teachable moments, many of which they share with their online followers.

So, when one of their daughters came home from school and told Shepard about a kid at school who uses the middle finger, it opened up a wholesome but amusing conversation that Bell documented on her Instagram stories.

Their daughter shared that she learned the middle finger means the F word, and went on to tell her dad how a male classmate constantly flipped people off.
