When some dude pops a woody and someone else notices his rock hard yogurt cannon then said first party must identify the underlying cause of his unnaturally erect wang. This is the "erection direction".

Most people signify the erection direction, or ED, with a subtle finger. If you're feeling bold use your meat steak to point.
Woah...Isaac. You have a massive hard on right now. Wheres the ED?

Yeah the erection direction is right over there. *points at Mariah*

When sporting a boner, sometimes it is more comfortable (or more ambiguous) to move it from facing downward (toward your feet) to facing upward (toward your beltline).

The Erection Direction Correction is the process of changing from one position to the other.
My boner was making a rather large bump in my pants, so I made an erection direction correction.

When girls start throwing their panties and titties start popping out during a one direction concert. The guys on stage get a one direction erection.
I was at this One Direction concert and these girls took their tops off right in front of me.
I got a One Direction Erection right away.
