Making someone prove they're a real gangster by seeing if they can hold their own in a real situation.

I told him to 'G'Checkin' and he had to fight my cousin to prove it.

She said she was a real gangster, so I made her 'G'Checkin' and she had to run from the cops.

He said he was from the block, so I made him 'G'Checkin' and he had to pull out a gun.
