An unexpected and/or uncalled for ejaculation of semen.
Doctor, I haven't been involved in any sexual activity for weeks, but I woke up to nocturnal emmision this morning.
Buy a
nocturnal emmision
mug!
A woman who looks as if she is a lesbian, and could or could not be one in reality.
I wouldn't bother checking her out. She looks like total les chow and you might end up being denied.
