Keri

Keri (קֶרִי‎) is a Hebrew term which literally means "accident" or "mishap", and is used as a euphemism for seminal emission. The term is generally used in Jewish law to refer specifically to the regulations and rituals concerning the emission of semen, whether by nocturnal emission, or by sexual activity. A man is said to be a ba'al keri (בעל קרי‎) ("one who has had a seminal emission") after he has ejaculated without yet completing the associated purification requirements.
