According to Know Your Meme, "aged like milk" is a catchphrase that mainly describes social media posts that have grown increasingly troublesome since their inception. When people throw their opinions left and right, some of them are bound to be wrong. Well, they might look fine at the time, but time truly shows which beliefs aged poorly by completely breaking modern social norms.

While the origin of the phrase is unknown, the earliest usage comes from a 2006 comedy special Jeff Dunham: Arguing with Myself. A puppet called Walter said "She's aging like milk!" in one part of the dialog. Since then, the clip received more than 4.2M views on YouTube and quickly spread to other platforms, forums, and threads.

If you ever felt slightly embarrassed about something you shared online, don’t worry. After all, social media is the place for us to vent about politics, culture, sports, our personal lives, and more, so you’re definitely not the only person to ever have a bad take. In fact, more than half of Americans (57 percent) say they have social media regrets. One in six routinely rue their decision to post at least once a week, with Millennials being the most regular offenders.

These numbers come from YouGov Omnibus' survey where they asked U.S. citizens about posting or texting something they regret. Many people admitted they were less anxious about sounding silly compared to a few years back. However, they are more worried about damaging their reputation at work — 22 percent said they are concerned that a questionable post might affect their career.

Results also showed that 14 percent of participants feared they may hurt relationships with family members or partners by sharing misguided images or messages. Plus, women were slightly more likely to feel troubled about social media blunders damaging their close relationships than men.

If you’re wondering how to make sure your social media posts won’t come back to bite you, always think twice before sharing something online. Ask yourself if there’s anything in this particular post or comment that could potentially hurt you in the future. Think about whether it might defame a specific view or lifestyle. Also, determine whether your words will actually contribute to the conversation or whether they will only create more noise.

Also, it’s always good to self-reflect and review your older media posts. It’s recommended to delete inactive accounts, provocative or controversial topics and discussions, and anything that might make you look overly cynical or mean. You have a larger audience than you think, so it’s quite easy to overshare and sacrifice your privacy. And just remember, if you ever end up posting something extremely cringe-worthy, there’s a big chance the members of the Aged Like Milk group will pick it up and will make sure to share it with the whole community.
