The activity of getting clunged, i.e. having sex with a sexy lady.

So called for the part of the woman that is ploughed, and how much fun the activity itself is.
Jack and Jill, went up the hill, had a load of clunge fun, but Jill wasn't on the pill so she got pregnant, became unattractive to Jack who had to start doing five finger exercises, and eventually she died and he turned gay.

Moral: Always go on the pill.
