Scary Movie Syndrome 

The state of mind after watching a scary movie. Symptoms include looking over the shoulder, checking under the bed, closing the curtains, anxiety of the dark and shadowy areas, sensitivity to sudden noise, and fears of normally non-scary objects (ie. television, dolls, clowns, etc.). The duration of this state of mind depends on how much of a chicken shit the person is.

SAS (Social Awkwardness Syndrome)

One who is uncontrollably awkward in social situations. This person, in normal everyday life, may seem rather normal, but when thrown into a social situation, the person is suddenly petrified, unable to speak or act in any way that is not completely uncomfortable for all who bear witness. This syndrome is sometimes hereditary, though typically develops in preteen years and lasts through adulthood. Not to be confused with an actual mental handicap.

"The strangest thing has been happening to me lately," said Shauna. "I'll be completely fine one moment, and when I enter a social situation, I suddenly can't act or speak in any way that is not completely uncomfortable and humiliating."

It's not a mental illness, I think you have been struck by the SAS (Social Awkwardness Syndrome)!" Said Susan. "It affects one in every three adults, and targets those who work in corporate settings, especially stock exchanges.

"Dread Pirate Roberts" Syndrome 

The everyday act of telling someone you can only have sex with them this one time only to come back the following day for more sex. Taken from the great movie "The Princess Bride" in which the Dread Pirate Roberts tells Westley (Cary Elwes) that he'll most likely kill him in the morning only to spare him every time.

Dude 1: Danielle said she wanted to have sex with me but she could only do it this one time. Then she came back this morning and we did it again.

Dude 2: Sounds like she's got a bit of the old "Dread Pirate Roberts" Syndrome

Study Abroad Slut Syndrome 

A mental condition that comes into the mind of guys waiting in the states for their long term girlfriends to return from studying abroad. It sets in about two months into the girlfriends studying abroad and causes their boyfriends to believe that they are messing around while in a foreign country. This can literally drive a man insane. However usually its true. Because why wouldnt their girlfriends fuck around with hot foreign guys that speak other languages that their boyfriends would never know about.

It can also apply to the females in the situation, whom in a normal environment in their home country would not even for a second think about cheating on their boyfriends, but third world countries are just so romantic some times that girls cant help but turn into study abroad sluts.

"Hey man when does your girlfriend get back from Germany?" "Fuck it, I know shes got study abroad slut syndrome over there!" "How did you find out?" "I dont actually have any evidence Im just making assumptions but I know im right!"

"Hey girls, Renzo is going to take me home for the night! Wooooo!" "Aww, did you and your boyfriend at home break up?" "Im only going to be in Chile once! Im a study abroad slut!! He'll be waiting when I come home"
