What is K-4?
1.
Thanks for nothing! K-4 is shorthand for the Thai phrase "kawp koon kee krahp" (man speaking) or "kawp koon kee kah" (female speaking). Both phrases literally mean "thank you for shit".
K-4, man! I told you to get her some nice flowers for her birthday and what happened? You wasted time with your BS and waited till the florist closed!
