The "dick" in the phrase "dicks out for Harambe" is referencing obscure street slang for a handgun. The suggestion is that we need to bring full arms to bear in order to avenge the 2016 killing of the silverback gorilla, Harambe.
Supposed to be a sign of respect for the late silver back. Is actually a lame ass excuse for closeted guys to see each others dicks without seeming gay .
Dicks out for Harambe! Thinks to self* thats sad fr but i just wanna see John's dick , but he cant know lol .
