to me it's kinda useful when you're trying to lay down facts or make something like a list, but it looks comical in an argument
for example:
"think of all the cool things that happened today
>i got a cookie
>i got a phone
>i got a cancer"
but when people try to use it in arguments like:
"you're an idiot and here's why
>you use windows
>you're a friend
>you're not cool"
it just looks ridiculous, as if people are trying way too hard
tl;dr: imo it's a colloquial thing, not for actual debate
