A dad joke is a joke typically involving a pun, often presented as a one-liner or a question and answer. Generally inoffensive, dad jokes are told with sincere humorous intent or to provoke a negative "groaning" reaction to their overly simplistic humor. Dad jokes are so-called because they are stereotypically thought to be those a father figure would tell to a child.
Urban Dictionary for Dad Jokes (pulling excerpts from 2 of the top 4 results, as the other two don't address audience or clean/crude nature at all):
An indescribably cheesy and/or dumb joke made by a father to his children.
The Dad Joke is a pejorative term to describe a corny or predictable joke, typically a pun. Generally inoffensive, Dad Jokes are traditionally told by fathers among family, either with sincere humorous intent, or to intentionally provoke a negative reaction.
From TV Tropes, "So Unfunny It's Funny", referring to the character trope of those that make dad jokes:
A character or show whose jokes are so bad, and whose sense of humor is so trite, corny, and childish that paradoxically you can't help but laugh at it... In English slang, this type of joke is commonly called a "groaner" or "dad joke"
Old 2023 article describing the difference between puns and dad jokes. First result when googling "pun vs dad joke":
One defining characteristic of dad jokes is their inherent uncoolness. These jokes often embrace corniness and intentionally steer clear of modern trends or edgy humor.
The website PunCity specifically calls out that dad jokes must have "innocent subject matter" in their article on dad jokes vs puns. (Once again, a top google result when googling "pun vs dad joke.)
So hopefully this has shown that the broad consensus across the internet is that dad jokes are family-friendly.
As an additional point, the current stance of this subreddit is that redditors are free to up/downvote NSFW jokes according to taste, but I would appeal to the mods that the structure of reddit and its feeds means that many redditors arrive at a post not knowing what community they're even in, especially when there is overlap in the scope of several communities. Therefore a majority of the upvotes on NSFW jokes are NOT saying "this is a good DAD joke", and are instead just saying "lol". The sheer numbers pushed by algorithms means these uninformed votes will pretty much always outnunber any community members that take time to actually assess whether they think a particular post is a good DAD joke. This structure de-emphasizes the clean humor that potentially makes this community unique, instead making it feel closer to the spamming of edgy humor that defines many of the default subreddits, like AskReddit and Jokes. Perhaps I am overly optimistic, but I would guess that this community would have (even) better growth and retention if it was more unique, not less.
