Ok, so someone does you dirty, the immediate phrase out of your mouth will be one of these two, depending on gender or preference:
Men stink!
Women stink!
along with various variations that include the words, jerk, bitch, bastards, asshole, c---s, wh--res, etc. (look I refuse to call women by those two words, and I will refuse to print those words simply because i feel it shows the greatest lack of respect to the gender.)
Now, in using generalized statements such as these, you only make yourself look foolish. Granted, you are angry at someone, but not the entire gender.
Now, would it not be simpler to take out an add in the local paper, put the person's name in it, phone number and list his/her misdeeds for all the locals to read? Not only would it make you feel better, but according to the latest statistics, at least 60% of any given market reads the classified ads. All you have to do is headline it in someway to catch the readers attention.
This tactic was actually used by a female in New York, and the resulting catastrophic impact to her ex's social life was beyond description. Not only did strangers read the ad, but co-workers (he was a lawyer) his secretary, who promptly quit, and his boss, (female.)
Now, I will admit to the fact that the males of the human species can make some really stupid errors, but so can the females. It takes one thoughtless action to really foul things up.
