A mirror is someone who really doesnt have a personality of their own so they find someone to copy and mimic them. This can range from clothing to speech and even hobbies. You might think that imitation is the sincerest form of flattery but in this case it isnt
"Dude why is that guy wearing MY t shirt how did he even get it?"
"I dont know man he just a mirror."
An irritating rich kid who believes that he is the best thing since porno. These people often tend to make incredibly lame jokes usually consisting of "April Fools!" Of course the only person who laughs at it is themselves
"Hey dude you're not gay. April Fools!"
"Man shut the fuck up, fole."
Idiots who tell others how to do their job when they arent even in the same company much less the same department usually found hanging out by dumpsters to pester well meaning people who try to earn a living
"That elfuc told me I have to use the Ajax for the windows..."
"Shes fucking with all the people now."
"Maybe she needs the peoples elbow to shut her up."
