Why Do Pimples Smell Bad On Popping?

Hello, Doctor. I have a pimple underneath and to the right of my vaginal opening, about an inch away from my anus. It s been a bit uncomfortable all day so I popped it after some pushing and squeezing. First, some stringy brown/yellow stuff came out, mixed with some oozy white/yellow pus and then I felt like a pop and more yellow/brown liquid and stringy stuff squirted out, then blood so I left it alone. The strange part is, the stuff that came out smelled like someone s really bad breath. I ve smelled it before like when someone I know had a tooth infection. What does this mean?
