A hair bump that appears on your head after you wake up in the morning. Any bump on you to appear randomly.

A fat lazy lump of fur. Typically a larger fat long hair cat.

The flump slept peacefully on the warm sunlit pillow.

When you're not exactly Fat, and you're not exactly Plump, you're Flump!

I need to lose some flump at the Gym.
