Muddy Plough

The act of performing vaginal sex after anal sex, which caused the penis to be covered in fecal matter. Similar to the Golden Plough.

Dude, I was Butt fucking my girl last night when she asked me to stick it her pussy instead. I pulled it out and saw it was covered in crap but stuck it in anyway, totally gave her the muddy plough.

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.
