Can not interpret what my roommate said to me this morning, is this gay love?

It was 6:40 this morning and my roommate and another male came giggling in from the outside. My roommate said "we both just banged Youkie and were giving rainbow high fives".

Now I admit I think I am pretty down with pop culture, but I am not sure what this means. So I turned to my friend the internet to help me try and interpret this.

I searching the term Youkie I found that it could probably be a couple things.

Youkie is a popular name in Japan. I found more females than males had that name.

I found Youkie to big name for dogs.

And Youkie is short for Red Sox first basemen Kevin Youklis.



As for the rainbow high five, I was not as successful trying to find an answer to what this means. All I came up with is this pair of Nike sneakers.




I'm not really sure what to make of all this , I am just glad that what ever happened didn't happen on my couch.
