In slang, “hedgehog” is often used to describe someone who appears tough, defensive, or unapproachable on the outside but is actually soft, kind, and caring on the inside.
Just like the real animal with its spiky exterior and gentle nature, calling someone a “hedgehog” is a playful way of saying they are protective but secretly affectionate.
Origins of Hedgehog (Slang)
The slang use of hedgehog originates from comparisons to the small animal itself. Hedgehogs are known for their sharp spines that act as a defense mechanism, yet they are harmless and even cute once comfortable.
Over time, people began using “hedgehog” metaphorically to describe individuals with a guarded personality but a warm heart.
