Drippin' or "dripping" is the act of eating a watermelon. This is generally reserved for an African American whom has a great taste for this juicy fruit. Originating within the southern regions of the United States in the mid to late century, many Negroes found themselves out of work and out of luck so they took to sitting on street corners crooning to women not of color while engaging in their most sacred of pastimes, drippin. The term was garnered by the act of getting the juice on your shirt while eating, as many of the Southern Africans would.
"YO! Tyrone! Me and muh Nigga's ur gunna go get drippin'! You in or out?!"
