An idiot who completely blocks traffic through an intersection by trying to go forward or make a left turn when there is clearly nowhere to go, then receives a violent orchestra of horns that rivals Beethoven's 9th symphony.
The horn junkie is a major cause of rush hour gridlock.
"Come on lady! *HONK* *HONK* *HONK*"
"That horn junkie is just asking for it"
"Mommy I'm scared why are all the people honking at us?"
