Here's a breakdown of how it's used:
* Expressing annoyance: "I forgot my phone, blooming hell!"
* Expressing surprise: "You won the lottery? Blooming brilliant!"
* Emphasizing a statement: "It's a blooming cold day, isn't it?"
* Used as a filler word: "You know, it's a blooming shame about that."
It's important to note that "blooming" is generally considered more polite than "bloody" and is acceptable in most social settings.
However, while it's not as offensive as other expletives, it's still informal and should be used with caution in formal situations.
