a post grunge pill head is a person who used to be a grunger who as they got older, broadend their musical taste, from being all about thrashing guitars, to liking drum n bass and electro beats from artists such as 2 many dj's and the klaxons
. If you can hear the sound of ambulances, wailing cats and repetitive singing (like somebody is accidently leaning on the sound keyboard) coming from your son/brother/boyfriends (insert applicable) room, it is most likely that he too is a post grunge pill head.
The post grunge pillhead will have no qualms about letting you know that you are a grunger.
Post grunge pillheads will most probably be part of woodcraft. Dont even get me started on that one.
