There is no history. They are just angry and into insults. You have to dig deep, and find the words that hurt. Saying FU or calling someone names just won't cut it. Everyone has a soft underbelly, find it.

Example, I pull up to the bank and park out front. Some guy pulls up behind my vehicle,blocking it, and is staring at me like a deranged lunatic as I walk into the bank and through the window while I am at the ATM. The car beside me pulls out of a handicap spot and he pulls in. He gets out of his car and is obviously handicapped but not a cripple, and as I am walking back to my car he screams at me "YOU DON"T LOOK HANDICAPPED!!" and I say "Nope, but you do" and get in. He goes from fucking losing it about me parking in a handicap spot and is now dumbfounded and obviously a bit shamed and as I pullout I yell "Hey, ******* look" and point at the ground. I wasn't in a handicap spot.

Guy is probably still crying.
