Sending me
Etymology
From the older sense of send meaning "to transport with delight," used of music in mid-20th-century jazz slang ("that really sends me"). It resurfaced in African American Vernacular English and spread widely on Twitter and TikTok in the late 2010s, usually as "this is sending me."
phrase · /SEND-ing mee/
Making me laugh so hard I can barely function.
What it names
It names the helpless, overtaken kind of laughter — the sense of being carried away by something funny, as if physically dispatched somewhere by it.
Example
The way the cat knocked the glass off and just stared at him — this is sending me.
Related idea
Stronger than saying something is funny: "sending me" claims the laughter has physically overtaken you.
