hitting the wall

The point in which a runner on a long-distance run has been drained of energy and his or her body seizes up. Very painful, very difficult to get passed.

He hit the wall. Oh shit he died.

Dick hitting the wall

When your dick is so big it hits the girls wall. 4 inches left of hammer a you can’t push anymore in. I hope I’m not the only one blessed with a curse of a disgustingly huge dick

Sean: well Its not even close to being in all the way you must have a shallow bucket.

hitting the study wall 

an invisible wall one hits when one has reached the point of study material saturation. All further attempts to study are futile and aimless browsing of the internet persists unabated.

After hitting the study wall, all I could do was look at rage comics on reddit until I woke up the next morning covered in piss.
