Boner Limbo 

The state in which a man does not have a full erection, but his penis is slightly harder than the norm. In this state, it is easy for the penis to become fully erect as a result of things that would not normally cause a boner, such as walking.

"Yo man, get your ass out of bed."
"Can't. I'm in boner limbo."
