Senkaku 

Senkaku is the name of some islands, as well as the name of a sex act.

Senkaku, as a verb, is the act of ejaculating on a girl's face, and afterwords she looks up at you and says "Dear, I admit... the Senkaku Islands belong to Japan."

"Last night I senkakued my KTV girl. It was pretty good and only cost 600RMB"

sengakuji

Sengakuji is a Buddhist temple located in the Takanawa neighborhood of Minato-ku, about 10 minutes from Shinagawa Station, Tokyo, Japan.

The graves of Shogun Asano Takumi no Kami Naganori and the forty-seven loyal Ronin are here.

Amazing story of honour, loyalty and Japanese culture.

Very, very few Japanese actually know of the temple, story or history.

Beautiful place when the sakuras bloom.

Foreigner in Tokyo - Did you hear the 5AM bell from Sengakuji this morning?
Japanese friend - What's a Sengakuji?

Sankaku Complex 

An anime site focused on sex, lewdness, and garbage media reviews, overrun by manbabies.

Average Sankaku Complex peruser: "You mean my favorite game meant for 9 year olds removed the man-eating, shitting-dicknipple monster? Censorship! Fuck Funimation! To hell with Crunchyroll!!"

When you shoot your load all over his insides because if you use phrases like "inside sankaku" you're clearly gay.

He wanted me to unload on his face but I gave him the inside sankaku instead.
