Synonymous to "pussy", "wussy", or simply a "non-drinking pussy". Usually labeled as an "EK" via email or other communication that needs vulgar censoring.
After a night of drinking someone might say: "I'm reminded why I quit drinking... man my leg was all charlie horse'd up this morning, still sore... my head aches, i feel dizzy, my stomach is woozy... fuck alcohol."

This person would be classified as a "Pytus".
