A very fine browser, perhaps the best one out there, with nicer users than Firefox.
Opera's users don't try to forcefully convert people like Firefox's users.

Though it only owns about 20% of the global browser market share, it's quite possibly the best browser available. Unlike Internet Explorer, it's secure. Unlike Firefox, it's fast. Unlike Safari, it actually works. It meets W3C Web Standards, and got a higher score than any other browser on the Acid 3 test.
Opera is the browser of choice, by Jesus Christ himself.

Trying to get attention at a bar, Theresa: "Can I have 3 vodka's please". No response. Dawn: "Opera it". Theresa: "Can I have 3 vodka's please" sung at the top of her voice in an opera style = instant attention & service.

1. The fastest Internet Browser available. Faster than Mozilla Firefox 2 and Internet Explorer 7 in all tests, but still only 1% of people use it.

2. Some gay kind of concert that rich people go to where they have to wear special glasses just to see the stage.
Example 1:

guy 1: Dude! Firefox is the fastest browser on the planet. I can't believe you're still using IE7.

guy 2: Dude!! Opera 9 is the fastest in all tests, and is more cutting edge than both of them.

guy 1: Oh... well I'm just going off of what my Firefox cult tells me. They didn't mention Opera.

Example 2:

Guy 1: Dude! Where did you take your girlfriend yestarday on your date?

Guy 2: I took her to the Opera. I wanted her to assume I was both rich and an intellectual.

Guy 1: Well... Did it work?

Guy 2: Ohhhh yea!
