How do you say "professionalism" in Portuguese?

So, I found a new apartment (finally!) and my new landlord and I went to a notary office yesterday to get the contract notarized. We took a number and waited for about 45 minutes for our number to come up (even though there were only 2 people ahead of us). Side note: This is normal, by the way, because time doesn't signify much here; it's sort of like a guideline... a very loose guideline. Anyways, we finally get called up to desk 14, I sit down across from this thirty year old Brazilian man and I notice right away his t-shirt. No joke, he's wearing a pink t-shirt that reads "no plastic. 100% real. just how i like em!"

Q: Ummm... when did it become appropriate to wear that t-shirt with dress shoes to your office?
A: Apparently when your boss doesn't understand what it says.

It's actually really funny because Brazilians LOVE to use t-shirts with english on them and many of the t-shirt are:
a) totally inappropriate and the person has no idea or
b) or make absolutely no friggin sense!

Some examples I've seen: A busty Brazilian blond walking down the street with the words "ABUSE ME"in bold print stretching over her breasts. The t-shirt I almost bought until I flipped it around and saw that it said "the most sex girl of all galaxy" on the back. huh???

It made me think, "Man! I wish America had a trend like that, were it would be really cool to use t-shirts with german sayings on them... and Germans would walk around laughing at the stupid t-shirts we'd be wearing" And then I remembered, hey that's not so different from the getting a chinese/ japanese tattoo trend except that getting hot dog juice tattooed on your lower back thinking that it means destiny provides asians with a lifetime of pointing and laughing at your dumbass while a stupid t-shirt can be removed, burned and later denied... Just don't forget to burn the pictures!
