#BACK:
Lexicalized form of the word "back." This form drops the letter
"a" and only slightly forms the letter "C" as the
handshapes move from a "B" to a "K."
This is a good version of the sign to use in statements like: "give
it back," "when are we coming back?"
Note: I sometimes see people doing this sign as BAK.
The back of your body. (Touch your back twice.)
Back: "Back of the line buddy." "It is in the
back." "...at the back of the room."
