皇居ランナー (koukyo rannaa)

koukyo= the Imperial Palace, rannaa= runner

Recently many people run around the Imperial Palace in Tokyo.

The peak times about 5000 runners are running around there.

So now there are rules for running- like you can run only counterclockwise and only on the left side and so on.

あげぽよ (age poyo)

age= short version of "age age" means more excitement (at club with DJ and so on)

poyo= no meaning just sonds cute?

First Japanese high school girls created and used this word.

And now it has become more popular.

You can use this on occasions like a drinking party "I'm having a fun so much!"

But usually only teenagers can use this word without embarrassment.

ガチ (gachi)

short version of "gachinko" means a game played earnestly.

This word comes from Sumo (traditional Japanese wrestling）.

But now people use "gachi" for anything done earnestly, extremely and so on.

e.g. gachi ota= well informed about something. ota is the short version of "otaku".

otaku= enthusiastic sub-culture fan (but it's not the only meaning...)

寝活 (neru katsu)

neru= sleeping, katsu= short version of activity (katsudou)

Many office workers don't have enough time for health care or beauty care.

They don't even have enough sleeping time.

So people take care of own body overnight while sleeping.

e.g. special stocking for swelling legs, hair treatment, supplements for intestines...

炎上 (enjyou)

enjyou= usually "go up in flames"

Recently people use 炎上 for blogs or Twitter and so on.

In this case, too many people criticize theose blogs so the person who owns the blog can't manage.

Many people tend to become emotional trolls in the internet community because they can be anonymous.

だてマスク症候群 (dahte masuku syoukougun)

date (dahte)= for show, masuku= mask, syoukougun= a syndrome

Many Japanese wear a mask for preventing spreading a cold or for pollen allergy.

But recently people who don't have any symptoms wear a mask too.

Because if they use a mask, they can hide their face and expressions.

So some people want to hide their face without using make up, others want to hide their ugly (they think) nose and mouth.

Many young people wear a "date masuku" in school too.

アラシック (arashikku)

ARASHI= Japanese famous idol group, +sick

People are almost sick because they love the J-pop band ARASHI so much.

ARASHI is part of Johnny & Associates Productions.

That company uses only male talent who can sing and dance as a unit. 

Many Japanese young girls or women like these members.
