Same in The Netherlands. 'Pik' is slang for penis.
Denmark and Netherlands using the same slang is easy to understand. But it's quite strange that in Brazil it means the exactly same thing.
Also doesn't help that the screenshot on the page includes the words "Reverse Cowgirl"...
Haha, unfortunately I didn't know that. Reminds me of how I looked up "Bing" in a chinese dictionary and found that it means "disease."
I must admit that I found the heading "Do more on the web with pik." rather amusing.
