Inability to fall asleep at night after taking evening naps. You come home from work and take a nap from 7-9. As a result, you can't fall asleep until well after midnight. The next day, the same cycle repeats itself and so on and so forth.
"You've crashed on the couch after dinner the last two nights and then haven't been able to fall asleep until 2 a.m.? You must have Evening Nap Syndrome (ENS)!"

The horrible feeling after a majestic bowel movement where you feel like your butthole is on fire, with no relief besides the gradual passing of time. The pain can sometimes be abated by either remaining on the toilet or walking bow-legged.
"Wes, you're walking bow-legged and you look so distressed. Is everything okay?"
"Dude, I just dropped the biggest log and I've got some serious Sore Butthole Syndrome (SBS). I feel like someone put a match to my sphincter."

Angry Young Man Syndrome usually occurs between young men aged 18 to 22. This often coincides with their discovery of beer as a breakfast substitute.
The effects of Angry Young Man Syndrome are: not calling or visiting your family, being gruff with your family when you do see them, not giving presents to family or friends on key holidays and birthdays, being grumpy when you don't get very good presents back, complaining about how poor and poverty-stricken you are after buying the latest computer game, listening to Angry Young Man Music, being cynical about everything and everyone in general.

White Person in Japan Syndrome is a mindset in which a white expat in Japan believes they will be worshiped and have numerous opportunities handed to them without working for it for no other reason apart from the fact they are white. This also includes the types of foreigners who visit/move to Japan with unrealistic, romanticized expectations of the country (usually caused by viewing too much anime), only to quickly become disillusioned early on and develop a strange contempt for Japan. Alternative names include “Foreigner in East Asia Syndrome” to be more inclusive and “White Person in Korea Syndrome” for all the Koreaboos specifically.
It's such a shame that Kendra's 'White Person in Japan' Syndrome held her back from making something wonderful of her time in Japan.

A darkly tongue-in-cheek “syndrome” that has been coined to capture the ugly fact that dissenting Russians are repeatedly being murdered via poisonings, mysteriously falling from towering balconies or just run-of-the-mill unexplained disappearances, at the behest of the Kremlin.
Putie the Warmonger has always flaunted his unrestricted power by publicly eliminating uppity Russians and blaming it on Sudden Russian Death Syndrome since it effectively scares the shit out of others who may be contemplating disobedience themselves.
