Why does no one use The Clown?

After all my years of playing I just went against The Clown and his little pink thingies for the first time. I split my DBD time half and half between killer and survivor, so maybe I just haven’t run into him (clearly I haven’t chosen him either). What’s the deal with him? I feel like a clown as a killer is an overused trope but that’s just my opinion. Are people truly scared of clowns?
