My real life recent examples:
"About to hang up our Christmas cards onto the wall and gutted to find our stapler is crap, doesn't staple anything, argh!"
Stealth boast translation: look how popular we are
"I'm so sick of getting asked for ID, I just want to buy my gin without ratching for my drivers license, I'm 35 and a mother of three for goodness sake"
Stealth blast translation: I'm soooo young looking
"Wow Holly got a Nintendo Switch for Christmas! 😱😁"
Stealth boast translation: we got her the Nintendo Switch, so we aren't thanking anyone but just want to show you all what good parents we are
