When you ignore someone in general chat unless they donate.
This can be unintentional for a busy streamer who hasn't read chat and the TTS is a way to get their attention, or intentional as a way to bait donations. This can be especially blatant when a streamer is responding to chat but intentionally not responding to a specific outspoken person.
They've been reading chat and must have seen my 10,000 messages, am I getting DonoWalled?
A person you hate intensely not because they deserve such hatred but because they serve as a focus for your general hatred. A healthy way to dispense with excess animosity.
Jake's not really that big an asshole. He just serves as my hate sink.
