Sorry for the confusion (to those who saw this before the edit). I originally had a question about walking the plank (or gangplank), which question turning out to be a brainfart I amend thus.

Looking at the senses for the verb plank in OED I see two American usages that I was unaware of, to wit:

2. trans. colloq.

a. orig. and chiefly U.S. To pay (money), esp. readily or on the spot; to lay (money) down in payment. Freq. also with out or up. Also occas. intr.

7. trans. N. Amer. slang. Of a man: to have sexual intercourse with (a woman).

I note comparatively recent cites for both senses (1990 and 2003). Are these common usages? I’m just surprised I’ve managed to miss them all these years.

I can’t recall having heard either one.

I’ve not heard of planking in this context, but I have heard of plonking, at lease in the first sense.

Me neither. Although I have read The World According to Garp, which the OED cites for the sexual sense, but I didn’t notice it.

Urbandictionary.com doesn’t list either of these senses.

I suspect these aren’t terribly common usages, although probably common enough that we’ll start finding examples through diegogarcity in coming weeks.

Me too. Didn’t notice or forgot.

Haven’t heard it.
