A tumblr dad is a person who worries about other people like a parent would. A tumblr dad is someone who in real life tells random people to wear a helmet, drink water, eat food, take their meds, come home safely etc. This is similar to a lot of Tumblr users. Tumblr dads most likely do not have kids of their own yet but take care of their friends like a parent would.
