After having sex with your girlfriend you keep the condom close so that after your girlfriend falls asleep you place your load in her hand and tickle her nose so as to make her slap your load in her face. Same thing can be done with whipped cream but not as funny.
Jay "last night I waited till my wife went to sleep and gave her a slippery slap"
Mark "how did that work out for you?"
Jay "she kicked my ass when she woke up..."
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.
