An expression derived from a leading brand name of crisps (potato chips) in the UK.

Taken from the sexual activity of a “Golden Shower” – This is the practice of urinating on a sexual partner.

Essentially a “Golden Wonder” is (hopefully!) an entirely fictitious sexual practice - involving the practice of urinating into a half empty crisp packet and bursting it loudly over a naked and prostrate girl.

The term itself is then used to define how “liberated” a lady’s outlook may be in the bedroom.
