The "(ﾉ ﾟヮ ﾟ)ﾉ*:･ﾟ✧" emote is a joyful and celebratory expression often used to convey excitement or happiness. It can also be interpreted as a gesture of throwing confetti in the air to celebrate something special. The phrase "This night is amazing" is not directly related to this emote but could be used alongside it to express enthusiasm about a fun or memorable evening.
