A slang usually used in texting. You say this when someone’s talking mad ish about you behind your back or when someone tells something they’re not supposed to say to somebody else. Hence, the abbreviation. Though you can use this in many scenarios, it just depends on the situation.

For example:
“I heard you been tellin Jessica my secret. yafab.”
