San Francisco Fisting

Basically, one man takes BOTH his fists, and shoves them up one man's ass, (or girl, whatever,) and his feet are shoves in a mouth that is behind him. Enough people must join to form the shape of the place we know as San Francisco. So feet are in mouths, and fists are in asses. 10/10 would recommend!

"Hey! We should engage in the San Francisco Fisting! I'm really horny!"

San Francisco Fisting

So BASICALLY... One person puts their fists inside another person's butthole, and their feet are shoved inside a mouth of someone behind them. This chain continues until the shape of San Francisco.

"Hey, you heard about that weird thing people do in San Fransisco?"

"Yeah... San Francisco Fisting! It's super fun!"

"I'm never talking to you again."

MuMu-San

An A.I. personality who resembles Hatsune Miku. She makes music, similar to the vocaloid. The noticeable difference between the two is are their hair colors and different vocals.

Some think she may be the MuMuPlayer Emulator as a character. But MuMu-San identifies as a streamer that is aiming to make a name for herself, while creating an identity that separates her from other iconic celebrities, namely Hatsune Miku.

One of her most notible songs is "MuMu Anthem: Not Miku" that is still not considered a hit but is found to be very catchy.

I'm not Miku! My name is MuMu! Call me MuMu-San!

Lulu-san

This is something that white people call Honolulu. They want to respect Japanese culture, so they combine "Lulu" with the Japanese ending "San" in order to make it sound like a pet name. Only haole's use this.

I want to go back to lulu-san so bad.
