telephone ear, telephone elbow, & telephone hand

After a long time on a regular house phone (not a cell phone), the ears, elbows, & hands get so tired from holding the phone they get sore.

That 5~hour phone call sure gave me telephone ear, telephone elbow, & telephone hand making them so very sore.

Jerkoff Elbow 

A tennis elbow type condition caused by excessive, frantic masturbation while viewing porn or frantic, fast masturbation caused by lack of privacy (in dorm room, in men's room at work, etc). Once the condition sets in on one arm, the jerker often switches to the other, to rest the arm which is suffering.

The porn jerker thought that the ice pack might ease his jerkoff elbow pain.

Sharp elbows 

In its most basic sense, it means pushing through a crowd.
But it is also used for a more metaphorical sense. E.g. for people who don't mind pushing other people out of the way or stepping on others to get what they want.
In other words, it means to be aggressive or ambitious, usually at the expense of others.

Young employees have sharp elbows these days. They dream more about management positions and high salaries than their older colleagues.
