(I'd never heard this one before. It resembles fall-like-a-lump, doesn't it? Flumping reminds me of the sound a pot of boiled red potatoes makes as I pour them already drained into my heavy clay beating bowl and the countertop resonates with thrumming, causing Twerpette to think someone is knocking at the door and sending her into a fit of barking.)
