What the Flump is Flump?! A flump is when two people are undecided with a fist bump or high five, and the fist hits the open hand to make a flump.Flump is also a creative agency specialising in brand identity, motion graphics and digital content based in London. (We're big fans of high fives and fist bumps in any combination too.)We have passionate, creative minds with a desire to craft design solutions that are engaging, enthralling and exciting. We love getting our teeth into juicy projects and collaborating with clients both big and small to make amazing stuff that's worthy of a flump at the end.
