sociotage
verb
To passive-aggressively destroy a relationship, especially by making oneself insufferable so the other party will break things off.
Often a case of weak cruelty.
Jelani had had a few pleasant dates with Antwan, but then the latter started flaking on plans and stopped returning calls. At first Jelani chalked it up to Antwan being busy, but soon enough it was clear that Antwan wasn’t interested in seeing Jelani anymore and was engaging in sociotage rather than coming out and saying it. Jelani stopped calling, and that was the end of it.
