you pulse your colon when you fuck?
??
so do all your turds come out with cock-prints stamped into them?
Do you understand the concept of pattern? Then you can stop here.
Weather has patterns. Which are made up of systems with the two factors: temperature which causes movement like air wind or water swirling, and percentage of humidity in the air which causes rain, sleet, snow, or mist, etc.
When you're a rabbit your colon is using the rhythmic pattern, much like when you fuck. Even though the complete fucking pattern also incorporates temperature, the only needed factor is the movement. Now, go find a partner and fuck. Look at the repeated pattern you make while tapping that fine piece of ass. Pretend you're at a therapist and demonstrate how you use the rabbits colon using the same rhythmic pattern motion, like when you explain your past sexual problems using the doll. As you're doing this demonstration the fecal matter moves from the rabbit's intestines from your manipulation of its colon, and as a result temporarily opens and shuts the sphincter, which results in uniform fecal pellets.
I'm not going to actually demonstrate this. It's your duty to do the appropriate school house rock performance.
