See fish food.
1. Slang term for male ejaculate.
2. Term describing post-flush fecal remnants.
1. The lip-cod was hungry last night, so I fed it some fish food.
2. Oh my! I spy fish food in my potty!
The remnants of shit that is left floating at the top of the toilet water after you've already flushed.
Not only does it stink, but I left you a little fishfood in there too.
