A rhythm game that requires the tapping/dragging of balls that appears on a random location of the screen, most good players are considered a virgin due to the pure skill and the amount of time they put into that game
There is a mobile version(actually I'm not sure) that has the same mechanics.

This game is normally paired with popular songs and anime backgrounds , some levels are just pure memes , and some levels are impossible to beat

1) Oklahoma State University, located in Stillwater, Oklahoma with branches in Oklahoma City, Tulsa, and Okmulgee. Its official colors are orange and black, as opposed to colors picked by OU matching the blood on their white away-game uniforms. OU fans would resent this.
2) School that jealous OU people and OU fans hate for its superior academics and 43 national championships.
I went to OU instead of OSU because it was cheaper, there is no other logical reason.

I wish I had went to OSU because the dorms at OU are shit.

A great free rythm game based off another rythm game no one cares about.
You can play community made beatmaps, if yiu dont know what they are its a map with ANY song.
The community is fucking garbage though, with 3 types of players
1) the guy who tries to reach the highest rank ever, usually has 100+ beatmaps in his pc. Usually fine.
2) the beatmap creator, they are either making those awful slow and boring bestmaps with no background or they are so obsesed that they make mind blowing stuff. These guys are nice...unless they are the last type of person aswell
3) weebs who joined because the game has anime like characters. These giys are the people who ruin the game, especially the chat. You see these guys playing fnaf beatmaps or one of their shitty sword art online covers. Their dictionary is of course filled with poorly pronounced japanese words...

Yeah its a good game
Player 1: hey bro look at my stats, almost to the top
Beatmaper: cool, hey play this map i made.
Weeb: OMG DO YOU HAVE SWORD ART ONLINE MAPS DESU :3333
Beatmaper: please fuck off

The beatmapper gets muted, cause the mute system for the chat is garbage.

Player 1: you are the reason osu is called the weeb game you miserable twat
