variation of chillin
From a reader:
The term "thugging" is not really a variation of "chilling". It's rather
a term used to describe the appearance of an individual. For example,
the phrase "she's thugging it" denotes that the female has an unladylike
appearance, usually that of a tomboy. For a male, as in "he's thuggin it
or yo, he's thugged out." denotes a guy who has a very ruff and rugged
demenor and appearance. This is usually attributed to his clothes. For
example, "Timbs" (Timberland Boots), a gold chain with a large
medallion, army fatigues, a stocking cap (women's stocking worn over the
head to produce "waves" in the hair), a "do rag" (similar to a stocking
cap), gold fronts (a little outdated but still typical of a "real
thug"), and just walks around with an "ice grill" (a mean looking face
with an unerring stare at any and everybody that passes within
eyesight.
I find this sight to be very interesting.
Thuggin is more a verb. To dress and act is a form of thuggin.
