A wanker is somebody who engages in self ego gratification (original term meant a participant in, er, “solitary vice”).
Sorry it it does not make sence!
But I did check the dictionary it is nasty and uncalled for!
There are many things one can say but just to throw something out for meanness show a very unkind soul!
Fight for liberty and freedom what for just to be mean and nasty?
How does that advance opportunity, hard work, and family?
