It's April Fools: I believed one of my bffs that someone I know went to the hospital because of a car accident and I fucking bounced
Why did they lie to you about this?
It's an April joke.
It is not smart to joke about someone getting hurt like this. Even if it is an April fools joke, it would probably be better to joke about something that is not someone getting seriously injured.
I'm just playing around, what is wrong with it?
Someone might get very upset about these kinds of jokes. You should not make jokes about someone getting hurt, even if it is April Fool's day.
