Why the fuck is this song titled "¯\_(ツ)_/¯" ?!

AND Where the fuck is the rest of it? I mean, there's an acapella version for you to hear but apparently these guys aren't releasing too many actual songs until they have visuals to accompany them. Interesting, marketing approach I guess... Lets see what they decide to do next.. If you aren't familiar with these 3 talented young men a quick google search may or may not help you.. Anyway.. here's this audio creatively titled 

"¯\_(ツ)_/¯ " 

 hope you all enjoy it...
