A person who is addicted to acquiring wonderful, beautiful, expensive, precious metal coins. A numismaddict is someone who is diagnosed as not being in control of their impulses or need to buy coins, even to the point of going broke to obtain them.

18. Transition Metal
A Transition Metal is an element from the D block of the periodic table which forms at least one ion with an incomplete d sub–shell containing at least one electron.

Used ambiguously by the WJEC to annoy students, especially Sam Jones.
Sam: 'Hey Alex, what's a transition metal?'

Alex: 'It's a D block element that forms ions with incomplete d orbitals.'

Sam 'Yeah, but the WJEC aren't really clear on their definition. It's causing a lot of confusion.'

Alex: 'That's exactly the type of shit those cunts would do!'
19. Tungsten
A metallic element on the periodic table with an atomic number of 74. It has the highest melting point of all metals and is otherwise cool.
When I said I wanted some tungsten, I did not mean molybdenum. Tungsten pwns molybdenum any day of the Muslim calendar.
