Right before you are about to fuck your girl you stand back about 10 feet and unleash the mother of all golden showers resembling the famous McDonald's golden arches.
The hugely popular, overrated fast food restaurant named McDonaldz where they insist on puttin' a 'Mc' in front of everyword spoken in every establishment.
Their big yellow 'M' is what this term referz to.
Customer: I'd like a coke please.
Staff: Thatz one McCoke.
Customer: Forget it ya McWanker, I'm off to Burger King...
(I know itz not a proper example but who givez a shit, this is funnier)
The woman lies on her back, you hold up her feet and begin thrusting your penis between the arches of her feet. When the timing feels right you lean back and urinate on her face.
I took Jessica out to breakfast after giving her the Golden Arches last night.
A variation of the golden shower. Specifically, when two men pee on another person from opposite sides, tracing golden arches in the air. Also possible for 2 women to accomplish, with some preparation.
Hans and Fritz gave me ze golden arches last night, und I had to towel off afterwards.
