In case anybody else is confused like I was: there is a plug-in for browsers that turns all mention of “cloud” to “butt”. Parent apparently has this plugin installed, and thus the “to butt” part is “to cloud”. (Users of said plugin will see me just saying butt a lot here :P )
I know I have one, that's why I never notice when the extension is on (I have it installed in Chrome, but I spend half of the browsing time on Firefox these days).
