Gangway 

This references the narrow passageway between two houses in a large urban area like Chicago.
Also used as a shout to clear a path in a crowded area, "Gangway, coming through".

When I came home, I walked through the gangway to enter through the backdoor of the house.

It was very crowded in the hallway so I shouted gangway, to get everyone to step aside so I could pass with my sick child.

gangway or sick bay 

US Marines having naval traditions and slang use the word gangway! for: move asshole!

Sickbay is where you go for any medical problem from a headache, to being run over by a truck, to being shot.

So the definition is: Move asshole or you will need medical care.

Gangway or sick bay motherfucker!

Gangwagon

An activity on social media where groups of community members send negative messages to outspoken individuals in support of a celebrity or friend.

Dave said a zero-star comment about an entertainer getting unnecessary cosmetic work done, then everyone jumped on the gangwagon saying he's a misogynist bodyshamer, completely missing the point.
