I got two problems here. They are both the sentances of a novel.
1. "Might as well get wasted, he thought, and rolled a small fat joint."
What's the meaning of "rolled a small fat joint" in this sentance.
2. "Johan plunged the nettles into the cold stream and shook them. If anything had been on them, it had no chance in the fast moving stream. "
Is that means if something bad on the nettles, they couldn't grow in the water?
