A brown angel normally occurs in the morning, whilst hungover and either trying to squeeze out a fart, or sometimes whilst sneezing, and even though you are sure that you have followed through, upon sneaking off somewhere to check, you are relived to find out your jocks are clean and it was just another case of the Brown Angel..
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.
