New parents-to-be dropping the happy surprise news of a pregnancy by referring to their future child with the "is yet to be born" pronoun instead of a more ambiguous one and waiting for the "wait what did you just say?" reactions.

Someone jokingly referring to themselves with the dead person pronouns just to highlight how horrible their current hangover is. A notorious aspiring ladies' man who keeps trying to pursue women in their 20s despite of approaching middle age fails to notice the insult when someone asks him when he's planning to get married, and uses the pronoun that implies that his ideal future bride may not even be born yet.

A mother whose young adult child just moved away from home for the first time, who continues to dramatically refer to their child with "may or may not be already dead" until the aforementioned child replies to her on facebook like "ma stop telling people I'm dead" and having her respond with "well how could I possibly know that when you don't even write to us? >:,C"
