Can i get a virus or spyware from the prank site googlehammer.com?

I was tricked by my friend into clicking ang going to the website. I had no idea what it was but when I opened it, it had an obscene image and it won't close. But I got to close it now. But I am still worried if this website will give me any virus or spyware? I am a bit uncomfortable now cos I use credit card and I'm worried that I might get hacked or something. I am using Mac btw. TIA!
