When you go to a website (usually via Google) and upon finding nothing useful, it wont let you leave by either:

A) Making you outsmart the website by pressing the back button twice in quick succession.

B) Giving up and opening a new tab because the above was futile.
"Damn, I wanted to find a picture of that CD, but this useless website Tab Hijacked me!"

When a girl/(some boys) use your computer and closes/reuse the tab you were working in.
