you use in work/on the internet/quotes that you then bring into different spheres?
as a restaurant worker i LOVE to unironically say "heard" to people in regular conversation (during a workday if a cook says something on the line its super loud so the expo person will yell HEARD super loud and vice versa so it makes no sense to use it outside of that scenario)
ive also said "behind" to people a couple times in public instead of "pardon me" or "excuse me" a couple times this one was NOT intentional
rtv quotes im a bit more hesitant about because the straight general publique will just look at you like 0_0 but "woo tequila" is a go to and "make it through the dehhh" has come into the rotation (can you name both references???)
OMFG me with "copy" I saw that like everywhere... but at my job we have walkies to communicate better with each other and everytime someone asks me to do something or says something, I say "copy" or "copy that"
