Imaginary Lat Syndrome

Imaginary Lat Syndrome is a common case of someone, typically a male, who believes they are rather muscular when in reality this isn't the case. Those with Imaginary Lat Syndrome can typically be seen walking uncomfortably while flaring their small lat muscles and tensing their arms in an attempt to look "jacked." In reality, it appears douchey and looks like a toothbrush has been shoved up their ass. Manlets are at high risk of falling victim due to overcompensation reasons.

imaginary friend

Usually as a result of not having much or any friends in reality, your mind creates an imaginary friend. Even the creator of an imaginary friend cannot see them, unless if they are on LSD, or just hallucinogenic. You're not nessecarily "crazy" if you have one.

You can just talk to them in your mind, they can think for you sometimes, you can ask them for advice or ask them to decide which movie you want to rent tonight. You can get into arguments with them, and you can have intelligent conversations with them.

But...

You can't kill them.

They might slowly fade away in time... but... I don't know...

Yeah.

Also.

You can completely change into your imaginary friend. Sad I know.

Some people have imaginary friends.

Imaginary Friend

A "character" created by the imagination to keep a person company. Sometimes, it can be difficult for the person to recognise that their "friend" is not real; at other times, they can be recognised as not being real, but are still used to offer comfort and company.

When I was three, I had one imaginary friend. When I was thirteen, I had five.

Imaginary friend

An imaginary friend is NOT the result of mental impairment. Actually, those with an imaginary friend are frequently smarter than most people (two brains in one). It's someone who is always with you, thus you are never alone. He knows you, your greatest desires and your flaws. So he usually judges you... but also the others around you. He comes often when you feel alone and need some help, or need to talk but have nobody trustworthy. An imaginary friend is really helpful, I advise you to try ! But pay attention, if your friend is comic, to not laugh too loud. People could think you're strange, even if it is a good thing, they're not really tolerant.

PS : Never let someone tell you he is not real, “Of course it is happening inside your head, but why on earth should that mean that it is not real?” (JKR)

My imaginary friend is Sirius Black, so he never died and is ALWAYS with me.
