@nina
Can you elaborate more pls 
@mur2501 oh it's like subtweeting. It's talking shit about someone's toot without mentioning it
@nina
Screenshoting a toot and then posting about it?
@mur2501 yeah, or just not mentioning a toot at all and tooting about it. Like if you tooted the toot at the top of the thread, my subtoot would be like "some people in the fediverse don't get subtoots 🤔" with no reference to yours
@mur2501 it's when you indirectly toot with another person and create a harmonic series that resonates across the fediverse
