Acronym for Post Ejaculatory Urinary Misfire. After ejaculating (either through masturbation
), if all of the semen
is not expelled, some may remain in the urethra
, developing a slightly more solid phase.
As the male attempts to urinate later (often the next morning), the urine may spray in multiple directions as a result of the blockage.
Man, I had to clean up my bathroom for 30 minutes this morning because I had a killer PEUM.
