Semen fever is when a man is so pent up and horny that even the ugliest candidate for sex will do.
Semen fever can be caused by busy work schedule and heavy amounts of cock blocking around the house. Cure ability is simple smack it and get your brain back before you bang a 3.5

Guy 1: hey bro want to hang out and hotbox today.

Guy 2: no man sorry but my semen fevers real bad
