If a character is truly evil or just wants to threaten another, they may throw in a snake-like hiss to scare them. While they may combine this in speech to form Sssnake Talk, they may just hiss alone to emphasize the threat. A cat hiss may also work to a similar effect, but is usually not as threatening.
