* A playful exclamation: Like "oh my goodness" or "oh dear." It can express surprise, amusement, or even mild annoyance.
* A filler phrase: Similar to "um" or "like," it can be used to buy time while thinking or to add a bit of lightheartedness to conversation.
* A way to avoid saying something explicit: It can be used to convey a sentiment without being overly blunt or negative.
Overall, the phrase is more about the way it sounds and its effect on the listener than about any actual meaning.
