Verbal abuse (also verbal attack or verbal assault) is the act of forcefully criticizing, insulting, or denouncing another person. Characterized by underlying anger and hostility, it is a destructive form of communication intended to harm the self-concept of the other person and produce negative emotions. Verbal abuse is a maladaptive mechanism that anyone can display occasionally, such as during times of high stress or physical discomfort. For some people, it is a pattern of behaviors used intentionally to control or manipulate others or to get revenge.
Many people who are into verbal humiliation will have one or more keywords or phrases that trigger them. It helps make them feel submissive, turns them on, whatever.
Having a specific phrase or word seems to be more common to men, while women will have a theme, but not a specific word, that tends to turn them on. For instance, a man I played with a long time ago really liked the phrase “breathe deep on the ether” (we did knockout roleplay), while many women I’ve played with like the idea of being slutty, so any word that evoked that feeling worked – slut, fuck toy, holes, etc. It’s a huge generalization, and won’t hold true for everyone, but it’s something I’ve found plays out more often than not for people in general.
The best way to find out what these are is to ask. Make it part of your negotiations before play. Also, pay attention to what they say during play – if they’re saying “I’m a filthy little slut” you can be pretty certain that those words turn them on.
