Acronym for Perfect Bowel Movement; a bowel movement which vacates quickly and smoothly without the need for exertion, leaves no mess behind, requiring no wiping, and leaves the sitter satisfied.
Some believe a certain (unknown) combination of dietary habits is the key to a PBM.
1. "I'm on a journey to achieve a PBM!"
2. "PBMs are good for the environment, as they waste no toilet paper."
3. "Wow, after that PBM I feel like I can eat a whole pizza, but that may ruin the chances of a second PBM."

"PBM" is an acronym for "Progressive Bowel Movement". It refers to those people that subscribe to, follow, and worship the pile of naive and un-reflective of-the-real-world policies from the progressive left. PBM members are usually well meaning, but are yet smug, arrogant, naive and generally have not strayed far from the false utopia of college campuses. Cities run by the PBM are either crumbling down, or already have. See example such as Seattle, WA., Portland, OR., or Detroit, MI. Colossal failures all, just ask the tax-paying locals and all of the RV street dwelling unemployed heroin addicts that reside there.
Funny, newly elected Seattle Mayor Jenny Durkan is so thrilled about her proposed "free college for all", yet true to PBM form, has not even given any thought on how to pay for this naive fluffy pipe dream. Economics class? Indeed, look into that!
