look up any word, like bukkake:
A weiney so big that it generates a noticable ammount of gravity
That silly clown has a massive permabone!!!!!!!

A sympton that occurs in males, often after having mass amounts of sexual intercourse. The male counterpart can not conceal his erection, therefore having a perma-bone.
Oh man, I went and visited the in-laws last night, and they wouldn't stop checking out my perma-bone
