(My brother sent me this email and link and it really is pretty good for a laugh!)
You don’t need to understand Portuguese to laugh out loud over what you’ll discover in this Brazilian saloon.
Click the link below, then enter your last name on the top line (Seu Nome), then your first name on the next line (Nome Do Amigo Zoado). You can ignore the email boxes.
The, click Visualizar!
How do they do that!?
Well, they know your name, because you put it in… 
What does the lovely lady say?
What you do is put your name on the top line and the name of the friend you are making fun of and who is the recipient of the email.
The gist of what she says is
" I got a tattoo, you want to see it?
Shows tattoo.
"Oh silly, don’t be like that. There’s one with your name as well.
“Calls over the big waiter.”
Just a small nitpick. Prenome is Portuguese for first name. My Portuguese sucks, but I’m pretty sure that Nome Do Amigo Zoado refers to the friend who’s going to find this in his inbox, which means that it’s his name on the waiter’s butt, hence the laughs!
I think I might send this to my wife.
Seu nome is Portuguese for name. Amigo zoado is Portuguese for the friend that you are making fun of.
