Paddycat
An Irish person who drinks milk like it's their main job. Their legs are stick thin, and their stomach is a milk tank. They don’t care if they look like a weird animal.
That Paddycat drank milk from the carton like it was a treasure map.
My uncle is a Paddycat. He drank milk until he looked like a giant balloon with legs.
That Paddycat drank milk so fast it looked like he was trying to beat the milk man.
