As I am building more sites with more asynchronously-loaded features, I am running up against a certain type of negative effect, which I am also finding quite a lot while browsing the web:
1) User enters the page
2) User sees an item s/he wants to click
3) User mouses to that item
4) Just before (micro-seconds) clicking, more content loads, pushing the target down-page, and another item into position under mouse
5) User inadvertently clicks on the wrong item, taking her/him somewhere wrong.
So many times colleagues are building pages that give rise to this effect that I need an easy handle to describe it. Preferably something short, humorous, and visually descriptive, the way "butt-calling" perfectly captures the problem with cell-phones in your back-pocket.
Does anybody have a term for this?
