Finding a Clown Name

Is proving difficult. I want something sharp and cutting, a little dangerous, androgynous, slightly sexy in a sort of cockney, I've-got-a-blunt-instrument-and-I-will-use-it kind of way. Character clown names have arrived more easily than this, my personal clown. Character clowns have a very specific context and when I name them I am contributing to an already established, overall mood. This feels tricky because I have to move inside the name with my whole self.

Anyway, I've considered:
Zipper
Stonk
Drip
Borbor
Clack
GusGus
Shit-for-brains (inspired by the Puritans religious phrase naming tradition)
Dilly
Cram(p)
Kramppp
Headlock
Knees
Tomtom
Schufti
Tracer
Nebuchadnezzar
Marmaduke
Lapsang
Frank(ie)
IkkleEcho

And as per usual, the internet provides a myriad of resources which are, in fact, no help at all.
