Casse-couilles is a highly vulgar compound noun (literally 'ball-breaker') used to describe an intensely annoying person or thing. It is invariable in form — the same spelling is used as noun and adjective and does not change for gender or number. Strictly informal register; avoid in any professional or formal context. The less offensive equivalent is casse-pieds.
