Heavy Ballsackalation is an extremely rare disease passed down by male-to-male contact like hugging (specifically the armpits touching). This is why, for generations, men have grown out their armpit hair to protect themselves from Heavy Ballsackaltion. Symptoms include a heavy ball sack, lopsided balls, purple balls, snowy semen, insomnia, and pimple break-outs.

Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
