Get the knucksmug. A small woodland creature in the shrew family. Many species exist, but the most common form, Grenicus albicans, was first discovered in India in the early 1700's. They are solitary by nature, but may be seen traveling in packs during the breeding season. Lately, they have become the rage of modern gangster rap music, possible because of their Tupacian nature.
One example of Grenicus albicans (Knuck to the lay person) has been discovered in Northern America, but it is believed to have been shipped in from India on a cargo boat. When captured, it screamed "WEST-SIDE IS THE BEST SIDE ALL YOU BITCH-AZZ PLAYA-HATIN' WANNA BE ME AZZ HOES"

Get the knucksmug. Name given to a person who the does one of the dumbest fucking things you've ever seen. Originated from a kid named Miles "O'Shaugnessy" Mohay and the theft of the word Knuck Knuck from some kid's big brother. One can also "Knuck Fuck", the extreme connotation of the word.
