A nickname given to the Coast Guard by the Marines. Usually said in a mocking manner due to the fact that the Coast Guard is rarely in combat and are instead mainly stopping drug boats and pulling six-pack rings off sea life. Contrary to the life of a Marine.
Coastguardsman: I’m in the Coast Guard
Marine: Oh, you mean Uncle Sam’s Canoe Club?
Coastguardsman: Huh?
Marine: Pussy.

While the dominant male is giving anal sex to the receiver he defecates. The giver is defecating and not the taker, and therefore the giver is packing (it in) and shipping (it out). The name derives from the story that Uncle Sam Wilson of Troy, NY was a meat packer during the War of 1812. The initials U.S. were inscribed on the meat packages to be sent to the Army, and it became legend that the good meat was from Uncle Sam.
I really wanted to go the bathroom and have sex at the same time, so I decided to perform Uncle Sam's Pack & Ship on the toilet.

Man: Give this soldier an "Uncle Sloppy Sam"!
Soldier: What the hell is that?
Man: It's where he gives you a handjob...with his mouth while humming the national anthem!

The personification of the United States as a male human. Uncle Sam is mostly known for the WW1 military recruitment poster where he points at the viewer with the text "I WANT YOU FOR U.S ARMY". His initials are also U.S, same as the initials for United States.
