A euphoric feeling, both heavy and light, that comes over you when thinking of Jen, and sometimes not consciousely thinking of Jen. The act of always thinking of Jen, and associated acts.
Touching oneself, calling your Jen on the phone, moaning...going on long road trips with Jen and staying in hotels that have red carpets, vibrating beds, and the playboy channel....watching commercials selling drugs to cure jenitis, and knowing there is no cure...
