What is "orgasm"? Please explain...?

For I am a terminator.. I do not know. Is it the same as applying Nutella to my neurological sensors? I measured my heightened sense of pleasure once I applied nutella to my sensors and compared it to that of an orgasm experienced by my sexy mexican housemaid. They seem to be equally matched sensations. Would it suffice to say that Nutella=orgasmic ruptures?
