As in rip.
A tear (laceration) of the wall of the vagina may be superficial or deep. Superficial tears do not require surgery and heal with minimal treatment. Deep tears are serious because they can cause a lot of bleeding. These must be repaired with surgery.
The most common cause of vaginal laceration is intercourse. This may occur during first intercourse in a virginal woman, or when thrusting is too forceful. A mismatch in genital size or insertion of a foreign object into the vagina may also cause a vaginal laceration. Thinning of vaginal wall following menopause or scarring of the vaginal wall after surgery or radiation may increase the risk for this injury. Straddle injuries on bicycles or climbing bars, water-skiing and jet-skiing injuries can also cause a tear in the vagina.
Vaginal tear(as in salty watery discharge) would just be weird.
