A donation made to a cause out of spite. Sometimes made in the name of the person you were arguing with about a subject, to the cause that person was against.
I made a spite donation in Kelly's name to Planned Parenthood after Kelly made insensitive and false remarks about abortion in a Facebook group. In fact, I donated a dollar for every comment she made.
When your relationship is not ideal and you want attention from elsewhere, you may seek a spite flirt.
I went to a Belgian bar and used the excuse of discussing beer flavours to spite flirt with the bar tender.
