This is the term used for a rash of bad decisions made after becoming very intoxicated from drinking George Dickel (a sour mash whiskey).
Can furthermore be used to describe a sensation in the penis during sex, where the male has a stone cold hard on and can't get off due to the dampening of sensation.
Man, I passed a trooper doing 120 on my Harley while on the way to bang someone's ol lady. No doubt that the Dickel tickle had a grasp on me..
When cheating on my girlfriend, no matter how hard I fucked, I couldn't get off. I had the Dickel tickle in my pickle.
