Spline 

The Spline is a sophisticated party act only performed by top tier beak lovers and ganja gurus. It involves two meticulous moves. One move requires a swift but conserved inhale of a perfectly prepared spliff. The THC must be then held in your lungs while simultaneously sniffing an Everest sized amount of cocaine through crisp, freshly rolled £20. If successful you have performed the infamous Spline. Toms and Jamess have a sacred duty to perform the Spline when cocaine and weed are present at a party.

"Oi mate, fancy a cheeky spline."
"Ye laaa I would love to smash a spline right now"

A combination organ between the spine and the spleen. One which doesn't exist, but you should ask the stoner people how it's doing anyways.

Hey Maya, how's your spline doing? What? Not to well? Oh, I'm sorry to hear that.
