A shower in which you only apply body wash to the top of your body, allowing it to trickle down to your lower body in order to wash it instead of applying it yourself. Named after Ronald Reagan's famous use of "Trick Down Economics" which is known for being a failure.
Johnny: Bruh, your ass fucking STINKS.
Ronald: Really? I have been taking trickle down showers every day for a week, I should smell great!
Johnny: Bro you legit have not cleaned your ass for a week.
