In a bizarre tweet on Sunday, Elon Musk challenged Mark Zuckerberg to a “d–k measuring contest.” This was a new low for Musk. The Twitter proprietor, a 52-year-old grown-up and father of 10, made the recommendation — complete with an emoticon of a ruler, in view obviously — hours subsequent to calling the Facebook prime supporter a “cuck.”

Since Zuckerberg, 39, launched Threads as a Twitter competitor last week, the two billionaires’ animosity has only grown. However, Musk’s most recent posts were the straw that broke the camel’s back for some long-term Twitter clients who have considered dumping the laid out web-based entertainment stage for its promising new rival. One person wrote, “This is getting out of hand.” Another person agreed, saying, “I’m getting a f–k ton of second hand embarrassment rn.” Others criticized Musk’s penis-comparing rant as “embarrassing” and “corny,” describing it as “middle school behavior.” Another person made a joke, “How do I unsee this tweet please?”

Meta, the tech conglomerate that owns and operates Facebook, Instagram, and Threads, among other social media platforms, has also been threatened with legal action as a result of the Tesla CEO’s tantrum. Alex Spiro, Musk’s attorney, wrote a letter to Zuckerberg on Wednesday, claiming that Meta had engaged in “systematic, willful, and unlawful misappropriation of Twitter’s trade secrets and other intellectual property.” A spokesperson for the company denied this claim.

However, it is evident that the online drama has not stopped people from checking out Threads, which became the fastest-growing online platform in history after gaining more than 100 million users in less than five days. Because of this, some critics have referred to Threads as the “Twitter killer,” and one business analyst has even stated, “The cage match has started, and Zuckerberg delivered a major blow.”
