Absolutely on vacay. Ick.
In the computer world, they say there is no noun that can't be verbed. Obviously, then, given Newton's First Law, there must not be any verbs that can't be nouned. I have to admit, though, that "reveal" as a noun does have a different sense from "revelation," which carries a connotation of aha!-ness absent from a "gender reveal." All-in-all, I give "reveal" a pass. "Invite," on the other hand, is a verb, only a verb, and nothing but a verb, so help me Webster.
