buckle up style

[cimorene]

I've seen analytical comments on Twitter and Tumblr referring to the posting style of "Buckle Up Twitter", but I wonder what would be the appropriate term for the rhetorical style itself (that is to say, the rhythm/pacing and melody, the frequent borrowing of clickbait framing/listicle style, the didacticism, and the heightened sense of urgency combined with a self-consciously artificial, vague chumminess - an assumption of familiarity that also makes clear we all understand the audience is actually strangers).

I am not sure if my perception is accurate (because Recency Illusion), but I have a sense that I'm seeing this rhetorical style being used gradually further and further from Buckle Up Twitter-style subject matter (ie less arguably urgent or important).
