plead the second 

Similar to plead the fifth (remain silent), except this refers to the Second Amendment (right to bear arms). In layman's terms, it means to whip out a gat.

When my P.O. was sweatin' me about why my whiz test turned up positive for coke, heroin, and 7 varieties of elephant tranquilizer, I had no choice but to plead the second and put his narc ass in his place.

Plead the second 

Delaying a household task because you need to take a shit (go number two).

“I don’t have time to mow the fucking lawn right now — I have to plead the second.”
