A sex slang used by roller coaster enthusiasts to show off how good they are at sex.

The name derives from the roller coaster of the same name at Kings Dominion in Virginia. This ride is known for its intensity and causing riders to grey out. As a result it’s not that popular with the general public but a favorite among enthusiasts. So in other words, you’re so intense during sex that your partner will likely grey out and feel super exhausted after a while.
