When you mog your anus and clench it so the poop comes out super skinny.
A very difficult practice if you have constipation.
Poop maxing defines and chisels your buttocks, just like mewing.
Bro I just poop maxed, my buttcheeks look like michaelangelo's.
Bro your ass so flat, come poop max with me.
Hey bro, poop maxing feel hella good, first the poop comes out in a sliver when I clench my cheeks, and my buns get so strong bro, try it.
