From Zergling. The weakest unit in the game Starcraft who has been fully upgraded with adrenal glands and metabolic boost. Becomes incredible fast moving and fast attacking, offsetting many weaknesses. Derived from the idea that the Zergling is "on crack".
In large enough numbers, a swarm of cracklings can easily destroy more powerful units such as Archons.

A crack-cocaine addicted duckling; usually results from a crackhead mother duck.
That poor crackling would only swim in circles, and fly upside down.

In the game of Starcraft, when the weakest infantry unit; a Zergling is upgraded with Metabolic Boost and Adreneal Glands. It then becomes a rediculously fast moving and attacking little bugger.
In large numbers, cracklings are almost unstoppable.

A more intense version of "crispy"

If something is defined as crackling, it is automatically superior to all other objects and beings.
A synonym to crackling is j'aime.
Mr.Toe: That troll ball is seriously crackling
Fish: Yes, Toe Man, indeed it is.

Mr.Toe: oH, but it feels so right.

A name for sheltered freshman from Boston University. Often used by older upperclassmen as a means to address younger freshman who exhibit qualities of craziness when given several tiny bits of alcohol. Much like Starcraft's Zergling when given Adrenal Glands and Metabolic Boost. Cracklings become crazy with tiny bits of alcohol due to their inability and inexperience to such stimulants.

Upperclassmen love hanging around Cracklings because they love watching Cracklings drink.
OMG that freshman is such a Crackling, I only gave him 1 shot of 151... WEAK

Zerglings with Metabolic boost, Adrenal glands, at least +2 attack, and +1 armor. They do so much damage so fast, that if done properly, they are not defeatable.
Dear lord! Those cracklings killed my command center in less than two seconds!

Those little white stinky rocks of funk that you cough-up from the back of your throat. Super-powered funk is released if they are mashed between your fingers.
Man, get a whiff of this funky-ass crackle I just coughed-up!
