Rainer.

From the term 'rain on my parade', used to describe someone, who, when you are feeling at the top of the world and generally high on life, has to ruin it all by an highly unnecessary little comment.

Person 1: you'll never guess what...
Person 2: what?
Person 1: I just won a million pounds on the lottery!!!!!!!!!!!!!!!!!
Person 3: You'll still have to pay tax on it though.
Person 2: just rain on his parade, why don't you?
person 1: Rainer.

Rainer Ami

A person who probably needs to rethink how they started getting into the internet. This person has probably gone through many breakups and knows they all weren't real relationships. They're probably also really horny, and absurd.

Person 1:"Look at that guy over there, he's pretending to be a ninetails."
Person 2:"Yep, his name is most definitely Rainer Ami."
