a girl with a vagina that sucks in all it comes into contact with, or, as the name implies, a vagina/vacuum
not to be confused with a whore, since the owner of a vaginacuum has no say over it's pure suction power, whereas a whore inserts various objects into her cooter of her own accord
a hint a woman may be the possesor of a vaginacuum is her inability to wear any types of pants without procuring camel toe
vaginacuums can come in many colors, shapes, and sizes, including highlighter yellow
When a woman has just completed her period and wants a little extra time before jumping back in the sack again.
After a week of abstaining from sex while my girlfriend had her period, I was flabbergasted when she told me that she was still on an extended vaginacation.
