1. To buy or sell an option and then later buy or sell the same option with a different strike price because one believes the price trend will continue. For example, suppose one buys a call option giving one the right but not the obligation to buy a stock at $10. One does this if one believes the underlying price will be above $10 when the option expires. However, if it appears near expiration that the option is well above $10 and likely will continue to, say, $20, one may buy another call option with a longer expiration and a strike price of $14 in order to capture higher gains. Rolling options may provide an investor with time to take full advantage of a prolonged price trend. It may be done with both call options and put options.

2. See: Roll over.

Archly inflating stereotypes beyond all recognition, Negrophobia made Mandingo seem positively politically correct, while recalling the psychosexual racial grotesques of Pedro Bell's album covers for Funkadelic.
Where the story is unusual perhaps is that it is performed entirely on roller-skates, with the two circus artists spinning circles - and, sometimes, lifting off into the air - as the characters roll in and out of each other's lives.
