Fauxicism

A false toughness defined by machismo and self-imposed isolation. The fauxic lives a life of constant, perceived persecution or threat without a fully formed sense of self. Fauxicism is marked by a projected carapace of imperturbability and lonely burden-carrying, though this may dissolve into snowflakery when the fauxic's sense of honor or respect is impinged.

Drinking yourself into an early grave to avoid talking to someone isn’t tough or edgy, it’s fauxicism.

There is upper-case Stoicism, lower-case stoicism, and then there is Fauxicism, the lowest-case stoicism.
