You can use the noun passel when you're talking about a group or a bunch of something. Your friends might decide to hire a bus to drive a whole passel of kids to an amusement park.
The informal passel is a great way to talk about a large but vague number of things or people, like a passel of cousins at Thanksgiving or a passel of puppies at the local animal shelter. Passel is a nineteenth century invention, a US dialect version of parcel, "quantity, part, or portion."
