The nickname Dirty Boat Guy or "DBG" is associated exclusively with the US Navy's Special Warfare Combatant-craft Crewman (SWCC, pronounced “swick”). SWCCs are more commonly referred to as Naval Special Warfare “Boat Guys.”

The true and complete history of the DBG nickname is unclear, but the battlefield bravery and late night debauchery associated with the title live on in infamy…
“Grab your kit, check your weapons, and fire up the boats. We’re expecting heavy seas and rain tonight… time to get your Dirty Boat Guy on.”

“I realize you Dirty Boat Guys are going out tonight and that’s fine, but I better see your asses here ready to drive fast and shoot hard by 0600.”

“You did what? Oh bro, you Dirty Boat Guy'd the hell out of that chick!”
