look up any word, like eiffel tower:
 
1.
the ring of period blood around the mouth of a female, especially noticeable on the upper lip; most commonly left after having vaginal intercourse while the female is menstruating and then pulling out prior to ejaculation in the female’s mouth, leaving a “blood mustache.”
She told me to pull out so I could cum in her mouth and I gave her a blood mustache.
