Definition: "05 06" is a slang term popularized by internet meme-makers and pun enthusiasts, often used to express disbelief, sarcasm, or mockery of certain events from the past decade.
For instance, "Oh no! 05 06!" is the phrase used when something has just happened that was not predicted at all. It's often used in a playful way, with people using it to mock those who predict things differently than they actually do. One unsettling example sentence is: "I'm sooooo excited for 05 06! I didn't know it would be this bad!" This phrase implies that someone was overly optimistic about something happening and then got caught off guard when it did not turn out as expected, making them feel like "nothing went right." It's a subtle way of expressing surprise at the unexpected outcome of an event.
