Female or male demon similar to succubus but does not engage in sexual relations with their human victim. Instead, the jaccubus visits men in their sleep and masturbates them until full release. This may happen multiple times, leading to physical discomfort, embarassment, and testicular depletion.
Babydoll: You feel like messing around a little before going work this morning, honey?

Me: Sorry babe, can't do it. My penis is so red and balls ache like a mutha...not to mention I was stuck to both the top and bottom sheets this morning when I woke up. Must have been visited by the jaccubus again last night.

Babydoll: You could have just said no. ::shakes head::
