Spitefit: Crossfit fitness regimen motivated by pure spite.
When you date your crossfit trainer/coach, subsequently get dumped by him via text message, and in turn join the only competitors gym in the area within hours of text receipt to ensure your continued hotness while ensuring you're not benefiting said scumbag in the process, that is called spitefit.
