Pop a Cesium pill 

A much more brutal version of "kill yourself."

It's so mean, because is you where to pop an actual Cesium pill it would blow you up from the inside of your digestive tract.

Joey: Heheh, hey Tom! I saw Timmy with your GF last night!

Tom: yeah? Well you can both go pop a Cesium pill, dickhead.

Joey: Jesus man! What the hell's your problem?

cassium

A cassium occurs when the engine in your old beater car continues to chug and sputter even after you switch it off.

How embarrasing, my car's engine is having a cassium again.

Cesium Shake 

A Cesium Shake is normally a mix of prescription drugs and a fruit-based drink (such as cider). It is thought of as the nicest tasting beverage in the illegal industry, and is commonly used for beginners in drugs or alcohol.

"I would never do drugs!!!"
"But you're drinking a Cesium Shake, Billy... Think of all that paracetamol..."
