A form of pleasure in which the male lies down flat on his back as the female sits criss cross apple sauce on his cock. The male then in the fashion he most pleases, rotates the female in complete circles on his penis until she continues to spin on her own, causing extreme enjoyment, similar to the Russian Helicopter.
The proper use in a sentence would be "We did the British Round-about last night and it was fucking incredible."
