A person Designated to stay sober and supervise people under the influence of Hallucinagenic Mushrooms. A Shroom Daddy is usually a close freind, or fellow drug user. People may take turns over the course of a week being the Shroom Daddy, in order to get their share of psychadellic fun.
EXAMPLES:
" I was tripping so Hard on shrooms the other day, If I didn't have my Shroom Daddy with me I woulda taken a dump on my parentsbed."
When your friend thats tripping on shrooms buys a ton of stuff because he or she thinks they are a millionare. In reality they go over on their credit card and get a crappy credit score after the trip.
My friend who thought he was a shroom dog millionare dropped his credit score from 760 to 430 in onetrip after buying 230 bags of twizzlers.
