持枪杀婊

'Gun in hand, killing a bitch.' It looks rather vulgar, even aggressive and hostile, suggesting intense dissatisfaction with something or someone. It's a very strong expression and is considered extremely inappropriate and offensive in many contexts. It could just express frustration, dissatisfaction with some women who behave improperly, in a figurative manner, but caution should be taken because it involves improper speech. Generally speaking, such nicknames are uncommon in positive, peaceful social environments.
