The origins of 'darkhorse' are somewhat vague but modern scholars agree it was originally an Essex term.
In it's simplest form it means "to have bum sex"
It is usually abbreviated to "horsey"
I'm just going out to feed the horsey
I can't sit down, I've been riding the darkhorse.
Fancy some horsey?
My dod Charles you are walking oddly tonight. Horsey?
v. the act of engaging in sexual acts with some one who has passed out.
n. a person who darkhorses
"I heard Julie and Marvin had sex last night."
"Actually, Julie was darkhorsed."
A song (a great one too, although not terribly well sung or produced) and the title track of the 1974 Apple album of the same name by the late, great George Harrison. Dark Horse was also the name of the visionary guitarist and composer's record label (distributed by the Brothers Warner), which he recorded seven albums for after leaving Apple (the label the Beatles formed in 1968) in 1976. Harrison himself was also known as the Dark Horse of the Beatles, a reference to a racehorse that people bet little on in the beginning, but who ultimately outshines his competitors in the end. When you have Lennon, McCartney and Martin as your mentors and Clapton, Dylan, and Shankar as three of your best friends, you can't help but radiate brilliance, as George did — and still does. As the Man himself sang:
"I'm a dark horse
Running on a dark race course
I'm a blue moon
Since I stepped out of the womb
I've been a cool jerk
Looking for the source
I'm a dark horse."

What about Paul last night? He had 10 cocktails, groped lots of girls, and ended up in a bar wearing only his pants and a reflective workman's vest. I never knew he was so wild - he must have been a dark horse all along.
