Jen-Cera is what you do to a friend's new date until you decide whether or not to like them. You treat them mean, make fun of them, and act like they don't exist until you know they are going to be around for awhile.
"I am just going to Jen-Cera her for awhile. We all know Todd has a different girlfriend every week and I'm not getting attached unless she is going to be around for at least a month."
