metal gear

1. Popular video game.

2. Used as a mocking expression (spoken in a rough manly voice) when someone repeats what another person just said as a question (Much like solid snake does in the metal gear series).

Person #1
"It's called Metal Gear"

Snake:
"Metal Gear?"

or

Person #1
"Hey look, a Plane"

Person #2:
"A Plane?"

Person #1:
"Metal Gear?"

metal gear

The best video game series of all time.

That's just my opinion.

metal gear

A nuclear equipped walking battle tank. Metal Gear Rex was held by the army, with legendary technology. The US marines later made use of Metal Gear Ray, which was amphibious, unlike the army's Rex. Metal Gear Arsenal was disguised as a rig in the middle of a lotta water. It was revealed to be more than just a weapon, containing nearly every piece of valuable information to the US government. It wasn't just a weapon, but the core of the country. It was guarded by a bunch of Rays. I don't know where the story goes from there, as I have not gotten Metal Gear Solid 3 yet.

Wow. It's a cool name that has been re-used for projects of killing machines and databases for the US government.

Metal Gear is something that people yell out when something bad happens. (refrencing Solid and Naked Snake from the metal gear solid video game series)

McDonald's drive thru: I'm sorry sir but our shake machine is broken.
