look up any word, like bukkake:
The particular predicament that occurs when you are tripping on cough syrup (aka robotripping, dexing, or tussing) and attempt to masturbate or fuck, but cannot perform to completion, NO MATTER HOW HARD YOU TRY.
I was robotripping all day and when I tried to jerk my chicken, I had a case of dex dick!
