How well do you know your texting slang?
Cap means "lie" or "false." The slang term gained popularity in 2018 as an alternative to the No cap term, which means "For real" or "No lie."
While Cap became somewhat popular in 2018, it gained a lot more exposure in May 2019 when NBA superstar Kevin Durant used it in a tweet accusing reporter Chris Broussard of lying about texting with him. People may also use "cap" in the context of "busting a cap," which means shooting a gun with the intent to kill a person.
