On God

On God is a modern slang phrase used as an affirmation, declaration of truth, or emphatic statement. It's generally understood to mean "I swear to God," "I promise you," or "I'm telling the truth." The phrase originates within African American Vernacular English (AAVE) and has gained wider popularity through internet culture and social media.

While the phrase explicitly references God, its use often doesn't carry the same religious weight as a formal oath. Instead, it functions more as a conversational intensifier, adding emphasis and credibility to a claim.

The usage of "On God" can vary depending on context and region. It's sometimes used ironically or sarcastically. A less intense version is "on god," removing the capitalization.

Alternatives to "On God" include phrases like "I swear," "I promise," "no cap," "facts," and other slang terms that serve a similar function of affirming truth. Its prevalence reflects trends in online communication and the evolving nature of language.
