The dap is a friendly greeting between 2 people to express solidarity.
It includes a wide variety of gestures, but it can be any handshake you have with a close friend. Most people create their own dap with unique snaps, slaps, and fist bumps—there’s no “right” or “wrong” way to dap someone up![1]
I don’t dap beyond fist/elbow bumbing, it would feel like appropriation if I tried. So, I can only point to sources. That hand clasp is very common from the ones I’ve seen in my sheltered life.
The elbow bump is because I’m often in gloves covered in chemicals… So elbows, if it has to be anything… Don’t dap me up, it’s awkward.






Oh, who: Americans, see sources I guess they’re all American. Where: I’ve heard it used in Britain too, so ‘the American hegemonic cultural west’ I guess. Since when: not a clue.
For what it’s worth, I heard the term ‘fist bump’ specifically for the act of fist bumping long before I heard of ‘daping up’. When I hear ‘dap’ it has almost always, I think actually always but I can’t be sure, included one of those hand clasps. A fist bump is just a ‘fist bump’. It’s strange what percolates out from the dominant culture.
When I hear dap up I just think of that ‘in the hood’ series time stamp 2:47. Dap up, that hand clasp thing, no fist bump.
