The act of a standing 69 in which you also penetrate the anal sphincter by giving the "two thumbs down" rating. This may be given in the event of a poor effort regarding the lower half of the standing 69. Or straight boredom. Also can be referred to as simply "The Ebert". Patent pending on the "Ebert and Roper".
Brought the spinner home from the bar. She had the oral ability of a teething todler. In response to her lack of skill during our standing 69 session, I decided to rate her performance by giving the "two thumbs down" rating, thus invoking the Roger Ebert.
