Hello, You would probably need to provide more context of its usage. However, whippy can be used as an adjective for something that is resilient, flexible, and springy. Derives from the word whip. That long flexible leather cord that can be used as a weapon. Take care.

Are you sure it wasn't "wimpy?" That's an adjective that means weak and feeble or cowardly. When I performed a search for "whippy", the first two results are a dating app of that name and an entry in the Urban Dictionary that I can't repeat here. I would ask you to give us more context, but...
