Squish would mean something is not straight. Out of alignment If you hadn’t properly hung a picture it’s probably squish. Now I’m straight. Now I’m squish. The first time we ever put up a basketball net in the driveway, unfortunately it was squish. We were always building cabins when we were kids. We had woods behind our house, we’d go out on trees and build a cabin and that was always squish. Skateboard jumps, they would have been squish. Shop class, birdhouse… squish.
