Nauseating

[Rihanna]

The accepted definition of [nauseating] is that it is an adjective meaning causing or [liable] to cause a feeling of nausea or disgust. What it really means, though, is something or someone has provoked a feeling of disgust so repulsive that you need to vomit so badly that it becomes the sole reason for your existence. The vomiting that occurs is so violent that at the end of it you are sure that your testicles are now on the top of your head and your arsehole has moved up to join your [eyeballs].
