spyrophilia

(noun) The joy or pleasure derives from squeezing pimples, blackheads, and other sebaceous skin eruptions. From the Greek roots σπυρίς (spyris), meaning 'basket,' something hollow, or 'pimple;' and '-philia,' a love of or a fondness for.

Whilst considered repugnant by some people, spyrophilia is a pleasurable and usually harmless activity for many.

Contrast with 'dermatillomania,' a mental illness related to obsessive-compulsive disorder and which is characterised by repeated picking at one's own skin, resulting in areas of swollen or broken skin and causing significant disruption in one's life.

Seeing a blackhead forming on Eloise's ear lobe triggered Ron's spyrophilia, and it was all that he could do to restrain himself from reaching over and attempting to pop it!
