A Gay Man who Sniff'z wenierz (Dick)(Not HotDogs..lol)
D-nice is a fucking peckerchecker!!!
A loose slang term for Navy Corpsman (medic) who takes care of the medical needs of Marines and Sailors, known for handing out the silver bullet (a magical cure all shot in given in the buttocks). Given this name because he or she is the first person a military member goes to when there is something wrong with the genital area of the body.
You're joining the Navy to be a peckerchecker?
