When a male submits his penis for oral sex (fellatio). "Knob" is a slang word or euphemism for head of the penis (glans); "get polished" (polished) implies agitation or rubbing, in this case full sexual excitation of the dick head.

When the male's penis head is swollen or engorged by oral sex, he has had his knob polished. In actuality, though, "get my knob polished" has come to mean "get a blow job" with the hope of orgasm included.

The term is not to be confused with "dip my wick," another penile reference that usually implies penile-vaginal or even penile-anal sex.

A person who does not orally polish the knob but instead leaves it messy with saliva and/or pre-ejaculate is a knob slob.

Solarpunk is a movement focused on a positive, ecological vision for a future where technology is used for human-centric and ecocentric purposes. It is a literary, artistic and aesthetic sub-genre and is also closely tied to eco-political activism. Solarpunk narratives have a distinctly positive and utopian foundation in contrast to the often dystopian visions found within other "punk" science fiction genres.
