Place it at the end of a caught-in-the-act moment, just after the rule is broken and before the reaction shot. Follow it with Bruh for a deadpan response, or pair it with Emotional Damage when the telling-on backfires on the tattler.

A short young voice delivers the line 'I'm telling Dad' with a smug, tattling confidence, stretching the threat just long enough to sound like a playground ultimatum. It feels petty, funny and instantly familiar, the kind of line that turns a small argument into a joke. The delivery lands as a playful warning rather than a real complaint, making it easy to reuse whenever someone oversteps.
