Munk and "making a pass"

i think i'll leave these for BPB

"Making a pass" refers to "coming on" to a person in a sexual manner. It is the older term, that I heard when I was younger.

I would assume that 'munk" is somehow related, but I too, will leave that to BPB!

Phoenix covered making a pass. Spanking the monkey is one of the most common slang terms for jacking off, i.e. masturbating. It was written as "spanking the munk" in this case just to make it more similar looking to "dunking the spunk." Spunk is slang for semen.
Actually, I rarely hear "spunk" used in its normal form, possibly due to it being easily misinterpreted (albeit knowingly).

"That athlete shows a lot of spunk on the soccer field"
"What?!"
"He shows a lot of spirit and determination"
"Oh."

Thanks.

I've been guessing if "BPB" mentioned by ebBeth and Phoenix meant "Bi-Polar Brain" and could not exactly figure it out.

Monger's explanation was interesting one, indeed.
