1a.

the backside, buttocks. A word dating from the 16th century or earlier which is currently an inoffensive, if rare synonym for bum, etc. (encountered in the com-pound 'pratfall').

1b.

the vagina. This sense of the term is an extension of the preceding, it has been rare since the 1960s.

2.

a fool, idiot, buffoon. A sharp, but not obscene term of criticism or abuse, in vogue in the 1980s. The word denotes extreme foolishness and is derived, in the same way as the synonymous arse or twat, from the previous senses of the term.
