Oh, deadnamed. It’s definitely an SJW term. Trannys, more specifically. From what I understand, trannies have a birth name in their original gender. They go all mental, and “change” their gender and name. “Deadnaming” is when you call the tranny by it’s original birth name.  Ex: Birth name: Sarah New name: Steve  If you call Steve Sarah, you have deadnamed the tranny.
