A Vietnamese slang term used to describe a pungent mixture of diarrhea and sperm. The term is used when two gay men engage in anal sex, and the one on the receiving end gets a sudden case of diarrhea and shits all over his partner's penis.
"I was fucking a twink's hot ass last night, and when I pulled out he squirted da han juice all over me. Fucking gross!"
