Chain Lightning

spell found in many video and computer games around 1990s and the first decade of the 21st century, wherein a lightning bolt strikes one target, then a second with decreased damage, a third, and so on, until its power has diminished beyond a tickle. Example games would be Heroes of Might and Magic 3, World of Warcraft, et al.

1. Solmyr's special ability is that he starts with the ability to cast chain lightning, one of the most powerful spells in Heroes of Might and Magic 3.

2. Elemental Shamans' Chain Lightning and Chain Heal spells are part of the reason why many World of Warcraft players choose them as their characters.

Chain Booting

The act of sniffing poppers (Amyl Nitrate - a drug favoured among the Gayers) from the shoe of a child's toy, e.g. Barbie, in a group, whereby the shoe is passed from Chain Booter to Chain Booter. Not to be confused with Arse Booting, which is a practice favoured among the Gayers. Also known as "getting on the shoe train". This act is in no way at all gay!

"Fancy coming round tonight for a few beers and a bit of Chain Booting?"

Chain caller

People who refuse to believe in this age of cellphones that there are people who cannot hear their phone rings or is constantly out of reception for more than 5 seconds, and will call nonstop until the other party picks up the phone.

I was bombarded by Jesse the chain caller while I left my phone in the car.

chain rule

In calculus, the chain rule is used to differentiate compositions of functions. It states that for any function f which is dependent on a variable u, and u is a function of a second variable x, then f is a function of x.

In Set Theory:

f(u)=u V u(x)=x V Vf(x)

In Calculus:

df/dx = du/dx(dx/du)

to differentiate (x+1)^2, one could multiply this out and apply the sum rule (derivative of a sum is the sum of the derivatives); but what if it were (x+1)^55? Suddenly the multipling out doesn't look so nice. To apply the chain rule, we must first define the functions. Let f(x)=(x+1)^55 and u=(x+1). Therefore f(x)=u^55. By the chain rule:
df/dx = df/du(du/dx)
df/dx = d/du(u^55)(du/dx)
df/dx = 55u(du/dx)
We earlier defined the variable "u" as (x+1). Now we substitute this in.
df/dx = 55(x+1)d/dx(x+1)
df/dx = 55x+55(1)
df/dx = 55x+55

chain letter

A virally propagated scam, formerly sent entirely through snail mail, but now more frequently sent through email. It operates basically as a pyramid scheme in which the recipient is urged to send a small sum of money to each person on a short list of names and addresses, with the promise that they will receive a lot of money when they rotate their name into the list, and the oldest name off of it, and mail the letter to everyone they know.

Some chain letters try to scam people even further, by instructing them rotate their name into the oldest position, so that the very next recipient will rotate them off of it, so that only the first names and addresses on the list will get any money.

"Yeah man, those Chain Rudders are gnarly"
