Halloween

CEO Brian Chesky said in a tweet the company would take steps to "combat unauthorized parties and get rid of abusive host and guest conduct".

"We must do better, and we will. This is unacceptable," Mr Chesky added.

Three people died at the house, in the city of Orinda, near San Francisco, and two more died later in hospital.

And modern celebrations has this event associated with darker colours.

But this Halloween, Port Moresby’s super club The Cosmopolitan is featuring a freaky pink party.

Favourite costumes will be altered to make this Halloween a pink one.

October 26, Cosmopolitan ladies night is encouraging freaky in pink, in support of breast cancer awareness!

Breast cancer is one of the top killers for women globally and in PNG.

And awareness is encouraged to break down the taboo associated with it.

The event is filled with entertainment:

Armed with Ellen DeGeneres' executive producer Andy Lassner, Ariana Grande stepped into the American Horror Story Maze at Universal Studios Horror Nights prepared for a sight—and more than a few frights. 

Killer clowns, spooky skeletons and a bevy of other creepy creatures lurked around every corner waiting to catch the pop singer when she least expected it.

Still, many look forward to ending the month of October on a spooky side, keeping an eye out for Halloween parties hosted in the city’s nightclubs.

Halloween is the evening before the Christian holy days of All Hallows' Day (also known as All Saints' or Hallowmas) on 1 November and All Souls' Day on 2 November, thus giving the holiday on 31 October the full name of All Hallows' Eve (meaning the evening before All Hallows' Day).

At least, that is the only plausible explanation we could come up with when faced with Cristiano Ronaldo's curious new mask!

The Real Madrid star flaunted the plastic contraption on Instagram, leaving many followers puzzled over its purpose.

Scary or just plain silly? You be the judge!
