the slang term referring to a greasy penis bubbly discharge which is caused when a male is sexually active with raggedy bitches; side effects include male queefing, irritating itchiness of the pee hole, and long term horrendous odor of the male genitalia
in a further note: this unpleasant experience has been named "duck sauce" due to the oddly familiar sound of a duck quacking during the male's queef stage included in the side effects listed above
Bro, please tell me you didn't dick down that raggedy bitch last night. She's been known to give others a gnarly case of duck sauce. That should go well with your special fried rice though.
