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"
