A white person who publicly talks a lot of shit (fighting words, accusations, trash talks, belittles, etc) and then gets confronted in an extreme fashion for said shit talking.
The individual then proceeds to panic at the unexpected retaliation and cowards for protection in any and all forms possible. The individual may also literally shit their pants
Person 1: Yo homie, Donald Trump was talking shit on Mexicans until El Chapo said he'll kill him so The Donald called the FBI
Person 2: no way, what a milk shitter
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.
Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.
