An ad that floats around the page, eventually settling in front of the information you're seeking and there is no (easily discernable?) way to get rid of it. I have only run across them on sites originating in the Far East, thank goodness they haven't caught on in the West!

Fly-In Ads are my #2. And anything else that makes me have to click closed to be rid of something I didn't ask for.

I don't mind rollover buttons...but mouse trails run me out of a site quickly. Just stupid....

The 'code' I hate worst of all is these dummies who think repeating the same phrase or keywords at the bottom of the page 1000 times helps them in their search engine rankings - and sometimes does!!!
