Nail and Tall Task/Tall Order

Today's slang is Nail.  Nail, as a verb, has some unusual uses that I would like to bring to your attention.  It has 8 meanings.  The first is the most standard and ordinary use of the word as a verb:
1. To attach something with nails: to fasten, attach, or secure something using nails

I nailed the broken fence post back into place.  It's not hanging loosely anymore.

2. To catch somebody who is guilty of an offense, prove the person's guilt, or have the person convicted (slang )

It took them five years to nail him for insider trading.

3.To prove that something is not true or valid and so stop others from believing it ( slang )

I finally nailed him about the "trickle down theory" of Reaganomics.  He's finally come to realize that tax breaks for the wealthy never "trickled down". 


4. To hit a target with projectile ( slang )

He nailed the 3 pointer with less than a second remaining on the clock to win the basketball game

5. To stop somebody and speak to him or her ( slang )

6.  To do something precisely or skillfully: to catch, hit, seize, or execute something with skill.   (slang )

8. To  keep something fixed or focused on something

This taxidermist was definitely given a tall order.

Today's idiom is Tall Task/Tall Order, both of which have the identical meaning: 
A formidable task, order or requirement
