I hate it when closed-minded people try to jestify something that I am urgently/vehemently bringing to their attention --- if I care enough about the wrongness/danger of the situation to make such a stew about it, I feel that they should receptively listen and promptly act upon what I am saying.
The ability to be a total swine/moron/idiot/liar and then when discovered to whine/moan/complain and make out that its everyones problem and fault but not yours.
"My God, I cannot believe it- first he sleeps with his sister while she was passed out- and then he did a total Justify on the situation!"
"I know I stole it, but it wasn't my fault- let me Justify!"
