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.

red!" - one of the "two gay guys from
Jersey" (Fred Armisen, Bill Haider) on TV show Saturday Night Live.
