Hiroshitma

A shit(s) so remarkably large it feels like squeezing a football out your ass. And when aforementioned shit reaches the toilet, it douses your ass cheeks with cold toilet water

*Word also applies to steady streams of diarrhea that make your asshole feel like its up in flames
Bob: You might wanna get your toilet a therapist

Jim: Why?

Bob: I just scarred it for life with like 3 hiroshitmas
