look up any word, like bukkake:
1. A man who likes to get another man drunk and then play Doctor. He will initiate anal sex and try to be serious and objective about the experience and anything he may find up there.

2. A Doctor that insists on checking your prostate every time you come in. He will typically leave his finger in a bit to long.

Part of speech: Noun
Alex: Dan stop being a Prostate Investigator!

Dan: I can't help it! I am drunk and like to pretend I am someone of the medical and/or gay persuasion...
