In Spanish, "Que" = What, "La" = The, and "Chinga" = Fuck. Que La Chinga is like What The Fuck, literally translated in Spanish. In Spanish, the phrase "Que La Chinga" actually doesn't mean anything, but it's good to use in situations where you can't say "What The Fuck" or "WTF", like at work for example. Can be abbreviated as QLC.
Que LaChinga man, the store closed like a hour ago and that customer's still in here, I wanna get the fuck outta here.
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.
