A person, who acts as if they have poop in their pants. A person, who's attitude portrays that they have a massive load of fecal debris in their pants, which will leave skids marks once removed. Someone who's personality resembles a dirty diaper of a small child with explosive diarrhea.
"Amy became poopy pantish after Kyle and Eric were loudly screaming nonsense as she was trying to focus."
