- In Clerks., he reveals to Dante Hicks that he had sex with his ex-girlfriend Caitlin Bree during their five year relationship and presumably has sex with Heather Jones (middle of the three Jones sisters) on a beach.
- In Mallrats, Gwen Turner, T.S. Quint and Brodie Bruce recall an incident at a costume party in which Derris and Turner had sex on a pool table. While Turner thinks it was a trivial event, Bruce and Quint remember the event very well because Derris and Turner were having sex on a pool table while dressed as Jackie Gleason and Burt Reynolds, respectively, from Smokey and the Bandit.
- In the most memorable sexual act, he and his friend Cohee London were in a three-way with Heather Jones's older sister Alyssa Jones during high school, which gave her the nickname "Finger Cuffs". When Alyssa is confronted by Holden McNeil about this occurrence, Ernest O'Donnell makes a cameo sitting next to them and listening in.
Derris' fate after Clerks has never been directly revealed. It is possible that, due to the fact that characters in Dogma and Jay and Silent Bob Strike Back ride buses labeled Derris, that he started a successful line of buses.
According to Jason Mewes, "Jay" is Jason Derris, Rick Derris' little brother.
