*** Etymology 2
US 1971,[1] originally by black soldiers during the Vietnam war,[2] associated
with [Black Power] movement. Originally an elaborate handshake, later
specifically a fistbump.
Verb originally [en]. Presumably [en],[3] or influenced by [en], [en],[4]
etc. Alternatively, from earlier slang usage as abbreviation of [en]. Also
explained as an [acronym], such as “Dignity for Afro People”[5] or “Dignity
And Pride”;[6] this may be a [backronym] or unrelated,<ref name="cassells"/>
but accords with phrasal use as “_give_ DAP” (compare “give respect”). More
speculative etymologies derive it from [vi],[7] though this is unlikely.
