I'm sorry but this is such a stupid name. Where did the author get this name from? Why would I say that in front of any female colleage or any non-technical layman? We already have a name for this and it is a "popup". Which sounds better? "Remove this popup" or "Remove this dickover" Be honest.
You could call them "clickovers".
Both of them are shorter than the "dickovers" or "clickovers" nonsense.
