It is similar to being cock blocked, but instead of getting blocked (or prevented) from scoring a potential hookup, you are being blocked (or prevented) from letting your poop out.
Getting "poop blocked" tends to happen in a work environment where another
party comes into the bathroom and occupies the stall next to you while you are trying to poop. You experience an awkward silence, making it too embarrassing to push your poop out since there would be a loud splash
sound going "plop, plop, plop" into the toilet. Additionally, the
person in the next stall now knows what your shoes looks like, which can be dangerous as he/she can now identify you around
the office.
Abbreviation: PB'ed

time today!

time...
Brenda: I had to retract so I can go back later to continue my extraction.
Erica: I gotta
go now... Hopefully I dont get PB'ed!
