Usually found on pedophiles as they carry too much weight promoting pedophilia, as nobody wants to have sex with an obese partner. Straight men usually get one.

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.
