I blow dudes that get pissed off at me a kiss, wink and wave. LOL!
1. The structure of that sentence is bad, if someone only skims and reads the first bit is suggests you perform fellatio on people who piss you off.
2. You don't happen to drive a Merc wagon do you? lol!
Had an incident recently with some idiot trying to run me off the road and then blowing me kisses, I pulled over to have a chat, he wasn't so keep after all and drove over a gutter, speed down a road and hide down a side street instead.
To the OP, getting angry at someone because they are pissed off at you isn't really logical. And by the sound of some of your other posts, i highly doubt you and your mate where completely innocent.
Plus, maybe he was looking for something to throw at your car, maybe he was looking for that sawn-off he used the other week to remove someones face with.
Best bet, ignore and drive on, if someone is tailgating you, pull over and let them pass or pull off down a side street or something if it's bothering you that much.
I usually just drop about 20kmph under the speed limit, they usually just go around and speed off.
