The phrase "dad goes out to get the milk" has become a colloquial expression or meme on the internet, often used humorously or ironically to refer to a situation where someone, typically a father figure, leaves for a short errand but takes an unusually long time to return.
The phrase originated from a common parental excuse, especially in movies or TV shows, where a father would say he is going out to buy milk but doesn't return immediately, leaving the family waiting and wondering where he is. It is a cliché portrayal of absent fathers in various forms of media.
In internet culture, the phrase has been used to describe situations where someone leaves or takes a break from an online community or social media platform, promising to return soon, but they end up being away for an extended period, if not indefinitely. It is often used humorously to poke fun at people who disappear from online spaces without explanation.
It's important to note that while the phrase is often used in a lighthearted and humorous context, real-life situations of absent or unreliable parents can be sensitive and challenging for those involved. Using the phrase online should be done with care and respect for others' feelings and experiences.
