Gubmint or Gub’mint (Gubment or Gub’ment)

“Gubment” has been a black dialect word for “government” since at least 1861. “Gubmint” has been cited in print since at least the 1940s. Both terms are frequently written as “gub’ment” and “gub’mint.” “Gubment/gubmint” has seen increased usage in the computer age as a mock name for the government.
 
Dialect variations of the word “government” include “gubberment/gubbermint” (from the early 1800s) and “gooberment/goobermint” (from the late 1900s).

gubmint 
Government, as used by right-wing pansies, used to “protest” progressive taxation against the capitalist class who stole the wealth from the working class in the first place. In the place of taxation, the right-wingers advocate charity, in other words, they ask the capitalists to be generous with other people’s (working class) money!
