Gar

[PussyCat]

A term used towards male characters and individuals who are so overwhelmingly manly that your own masculinity is absolutely buried, leaving you naught but a whimpering, swooning girl-child before them.
Originated in [4chan]s /a/ board. A poster was describing his feelings towards the Fate/Stay Night character Archer, and mistyped gay as gar.

[Sarah]

To like a male character or individual for being a cool, powerful badass.

Derived from a typo (gar instead of gay) on 4chans /a/nime image board when referring to Archer from the H-game and anime series Fate Stay Night.

When a male character is so manly that otherwise straight male viewers find themselves attracted to him, they are said to be GAR for the character.
Nowadays GAR is used to describe characters that have reached the utmost levels of manliness. Said levels being judged looking at:

The characters build (the more muscles he has the manlier he is).
The ability to shout his attacks (GETTA BIIIIIIMU!, ROCKETTO PAAANCHI!, ATATATATATATA!!), though this is not necessarily a must.
And finally the power to bring manly tears for the viewer (through either a speech brimming with awsomeness, a manly death, the end of the series, all of these combined etc.).

1. To have a mancrush on someone.

2. Something incredibly manly.

An ancient family and/or order of ray-finned fish. Order Lepisosteiformes and family Lepisosteidae, which contains about seven species. They have a elongated snouts and bodies that are heavily armored by ganoid scales, and their jaws are filled with many small, sharp teeth. For some reason, their swim bladders can function as lungs and most of them occasionally come up for air. All gars are relatively large fish, but the alligator gar is the largest, sometimes even growing up to 9.8 feet in length. Gar flesh is edible and their hard skin and scales are often used by humans.
