low- or dirty-minded

glancing at the idea that a person's mind is in a muddy trench, with connotations of both trench-foot and a degenerate's trench coat
When he said that a slip of the return key halfway through typing "milfoil" in an internet search would transform an invasive aquatic plant into a filthy acronym, his friend laughed and said, "Trenchy minds think alike!"

He replied, "Stop right now! I don't want to hear any jokes about olives, whales, sunflowers, safflowers, or corn."

Trenchy is a red-headed dwarf who digs trenches. His beard and hair are long enough to wrap around his entire body, so as a result, he rarely wears clothes and typically resembles a ball of hair with arms and legs sticking out of it. He also doesn't speak and communicates entirely through grunts and hand gestures.

He is an immensely powerful druid, and a fabled hero of olden times.
Trenchy, haven't you already dug enough trenches today?

Come on Trenchy, I can't understand your answer to my previous question unless you say words. Oh that's right you can't.
Trenchy, you've saved us all once again. Please accept this diamond shovel as a small token of our gratitude.
