A tiny amount of weed, like the crumbs you leave on the couch after you eat a whole bag of chips.

Yo, I only got a lid of weed, so don't expect me to get high enough to fly.

I asked for a lid, but this is like a speck of dust compared to what I wanted.

My mom says a lid is like a snack, not a meal.
