Black History 365 | # 51 - The Dap April 19, 2024 Black service members in Vietnam developed the dap, a combination of hand and body gestures as a nonverbal form of communication. The dap could be as simple as tapping fists and shaking hands or as complex as dozens of gestures with the hands punctuated by slapping chests. Whatever the elements, the dap—an acronym for “dignity and pride”—was a symbol of solidarity and survival, an expression of black consciousness and a commitment to look after each other on the battlefield and in camp.
