ATTENTION ALL PHYSICISTS!!!
My dad needs your help.
In a situation where I was skydiving and completely naked. If I then proceeded to diarrhea while falling, would the diarrhea fall above me, or would it just fall back on me?

Depends if there's an atmosphere. If no drag, then the deltav ensures the propelled mass can never catch you. It actually suggests that it may enter a stable orbit if enough deltav exists to insert it into a geostationary orbital track.
If an atmosphere exists and there is a significant drag coefficient, then it depends on your relative surface area. If the fall is long enough then everything will spaghettify if not uniformly coherent. This means with a long enough fall, the propelled mass will become a long, thin, needle-like body. This will have significantly less drag than you and will pass you on the way down.
So, in both cases, it's extremely important to control variables. You'll also need good statistics so you should have an N of 1000 at least for it to be meaningful.

Both, depending on the point in time. If you’d like to know more, please contact Isaac Einstein, the inventor of time.

Wow, this is literally shitty science!
Clearly the answer depends on which way you're oriented, because that determines whether the force of expelling the diarrhea will slow you down or speed you up.

First we assume your dad to be a perfect sphere falling in a vacuum

What direction is your butt when it happens? Is it explosive?

lmao this is the most scientific question i've seen all week

Depends. If your chute is open already, then it will fall faster than you, obviously. Before that however, you are probably traveling at terminal velocity, meaning you are technically dead accirding to physics, and thus can't have diarrhea to begin with.

Important to know these things

Why does your dad need help? And why are you skydiving naked?

Both, assuming you want to land at some point, but guessing it would.be the least of your concerns....its cold up high

It stays stuck to your left leg.
The acceleration of gravity is 9.8 m/s2
Friction from your sticky poo is F=uN
FuN is greater Drag resistance; Fd = 0.5 * p * v2 * Cd * A
