Countersignaling is signaling that a naive observer might take to mean that one is the opposite of X, when in fact, one is X, used as a means to signal that one is, in fact, X. For example, aristocrats ("old money") may forgoeforgo gaudy bling in order to signal that they are not nouveau riche (new money), which may lead some people to incorrectly assume that they are not rich.
