N.) An ad
that pops up after you close another ad
A.) kamikaze added
The act of being kamikaze added.
A common marketing tactic
in the online world nowadays is, when a person clicks on a web page, a certain element is loaded, or a web page is closed, a new one is opened. This can result in endless loops of ads, where closing one simply opens another. In common terms, it's a big fucking load of bullshit topped off with a dingleberry cherry. Any company that uses this tactic deserves to go bankrupt and its employees shot on the spot.
Kamikaze ads are the ultimate product of a life spent training to be a douchebag.
