This word is already defined, but it means to remove one's own genitals (with a knife or their teeth). It is said that you can see more than enough of this on Pain Olympics (I don't even want to watch it and find out...) Honestly, anyone who engages in this instantly deserves a Darwin Award...
Two people observe a crackhead with a knife.
Person A: Holy shit! He's got a knife!! What do we do?
Person B: Stay out of sight. Be ready to call the cops if he starts something.
Person A: Sounds like a good idea. But, what if he attacks us? Do you know any martial arts or have a gun?
Person B: Yes and yes. For now, we just watch...
*a few moments later*
Person A and B simultaneously "puke their guts out"
Person B: That crackhead just performed self-castration! Quick! Hand him a Darwin Award!!
Nickname given to bales of marijuana thrown overboard or out of airplanes. Origin is reportedly from members of the US Coast Guard in the area of Southern Florida.
A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
I had a trucker's tan after driving for 10 straight hours on a sunny day.
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.
