“On God” or "On my life" are old school alternatives. Originating in Chicago slang, this is an example of "marching" (which basically means “swearing on something sacred”). There are a lot of ways to do this: you might say “On my kids” or “On my life” as way of expressing that you’re serious and telling the truth. This phrase is used in the same way as "no cap."^{[4]

- If you listen to hip hop (and drill music specifically), you’ll often hear the phrase “on foenem." This is another common example (it’s short for “foe and them”—the “foes” are a gang).^{[5]

If you don’t want to offend anybody by dipping into some lingo that’s a touch outside of your life experience or natural speech, just say “for real,” “I’m serious,” or “I’m being honest.” It’ll communicate the exact same thing without rubbing anyone the wrong way by dropping unnatural slang.

The “cap” in “no cap” probably refers to a limitation. People may talk about a cap on the number of deer people are allowed to hunt each year, or a cap on the amount of carbs they can eat a day to stay keto. So, if people use “no cap” to mean “I’m not lying” in scenarios where they’re saying something potentially over the top, it makes sense that someone would make the connection.^{[6]

- Another classic example is a “salary cap” in professional sports, which refers to the maximum amount of money a single player can be paid.

The term was popularized in 2017 by Young Thug and Future.

- Earlier references to “cap” can be found all the way back in Geto Boys and UGK’s music from the 1980s and 1990s.
