I have a memory of this happening to me in elementary school, though it wasn't the result of diet pills or fish. I was pretty sick that week and that exact orange discharge came out of my ass and onto my pants. I got up off the couch just in time for it not to leak through, and immediately threw my whole outfit in the washing machine before crying in the shower for about 30 minutes. I didn't tell my family and I especially didn't leave a mess for someone else to clean- and I was like, 8.
