plow/plough a trout

Plow in this case being a verb meaning defecate and trout being representative of human excrement.

This is gonna suck, I haven't plowed a trout in a week.
I ate Thai food last night and this morning it felt like my trout had spines.
This pond is for release only. All trout catchers will be shunned.
