2+2

.22 caliber.
A small rimfire cartridge, used for target shooting.
Three variations of .22 caliber exist: .22k (short), .22lr (long rifle), and .22WinMag (Winchester Magnum).
Sometimes used incorrectly to refer to a derringer, which is often chambered in a larger caliber.

2-10-2

2-10-2 (or 2/10/2) is U.S. Navy slang for a female who is unattractive, but then becomes "attractive" when she joins the Navy. Women in the U.S. Navy (and the other branches of the U.S. military) generally get more attention than on land, because of the number of males to females.

"She was a 2 before going out to sea, a 10 out at sea, then back to a 2 when she returned."
"She's a real 2-10-2"
