headbutt the buffalo 

An euphemism for cunnilingus, oral sex, an act performed by a person on the vulva and/or vagina of a female, the opposite of fellatio. The term was created by “The Man” and has become popular due to its frequent use on the legendary podcast Slacker and The Man. It is important to this podcast not to offend their sensitive listeners, many being doctors and lawyers.

Terminology: A headbutt is a strike with the head, typically striking a sensitive area of an opponent. A buffalo is an animal that is the size of a very large cow, with shaggy, long, black/brown fur. If you haven’t figured it out yet, buffalo is another euphemism for that treasured part of the female anatomy, the vagina. Put the two together and it is easy to create an image in the mind of a man charging with his face first into a lady’s lap - the beginning of oral sex on a woman.
Mashers: "I have a 30 minute minimum when it comes to sex."
The Man: "Does that include headbutting the buffalo?"

The Man: "Ever headbutt the buffalo?"

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
