insominate
Refers to da "fourth base" action dat you perform wif your bed-partner in da middle of da night because one or both of you couldn't sleep for some reason.
Allowing your main squeeze to insominate you may indeed cause HIM to become sufficiently relaxed and "worn out" to fall asleep, but YOU may be kept awake YOURSELF afterwards from wondering if he either got you preggo or gave you an STD!
