A coup d'etab is the act of deleting all the tabs that are open on your browser in one fell swoop. It may also be applied when doing it for a tab-hoarder's infinite amount of open tabs.
I was on my boyfriend's phone last night searching for something when I saw he had 23 tabs open! I did a coup d'etab and closed them all at once.
