A dirty guy is a guy who smokes grass, eats ass, and dates a fucking 10, literal 10, with a hell of a lot of sass.
Did you see that dirty guy? How’d he get with her? Must have big hands, I guess?

A man with too little pussy and too much coc. He will often be attracted to specific types of penises, with smaller sizes attracted him more due to a younger body generally being attached to it.
That dirty gui has too much coc to know where to put his own!

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!”

A man who hasn't cut or washed his hair since the 4th grade. It wears the same shirt for about two weeks straight before changing to a new one. Drives a 2006 Suby or a big black van. He can't grow a beard but he can grow a mean scum stache. His scum burns (side burns) really tie the whole outfit together though. The Schweppes is the most important part though. It drinks a 2 liter of warm Schweppes every single day
Everyone likes Dirty Schweppes Guy
