Its the name of the most iniquitous gang on the far Robloxian land. Its mostly used in a sentence to determine if the person you're talking will cause you to have a bad time or not. If they are part of the gang they should be avoided because they will try to make a rise out of you and they'll share it with their friends.
Person A: Hi dude! Do you happen to be apart of the Evil Gnag ๐๐๐?
Person B: Yeah why?
Person A: Sorry I gotta go bro. Maybe next time.
Person B: Yeah why?
Person A: Sorry I gotta go bro. Maybe next time.
