When a player in a shooter has extremely good aiming accuracy, we can infer that they are an Osu! player and have therefore developed the 'osu! aim'.

These are the kind of people who can click faster than you can even think.

When a player is so good at aiming you might call hacks -but you should probably call it osu aim instead.
-Omg dude, is that osu aim?
-Yeah bro I've been playing for years
Osu! Aim= when someone who plays osu is an extremely good shooter in a video game

A title granted for players who are very good at osu! - a rhythm game where you click circles to the rythm of a song.

First appeared as a congratulation message for completing the the game tutorial, the phrase is now used as an inside joke in the osu! community. It is said that only the nerdiest of osu! players are worthy of such title, such as the famous osu! player Kurokku.
Ah, I see you have beaten the tutorial and starting to get a feel for the game, you're well on your way to becoming an osu! rhythm champion!
