Man has a hardcore one-man rave in Sydney University law library

A Sydney University law library was turned into a rave for one man and surprisingly no-one told him to keep it down.

He kicked off the prank by asking a student for a spare set of headphones, before pulling out his "skitz speaker" and raving away with a phone plugged into a loudspeaker.

Students did their best to focus and study as the raver danced between bookshelves and all around the library.

The man behind one-man rave is known by the name of ‘SlenderTheMan’ on Facebook and has already hit over 300,000 views online within 15 hours.

The Sydney University law library isn't the first to witness the hard-core raver - last week he unleashed his madness in the lobby of UTS “looking for the best place for a Hardcore Rave meetup” before stomping away.
