It was the night before New Year's, and all through the fucking projects
Not a handgun was silent, not even a Tec

from GZA (Ft. Inspectah Deck) – Cold World Lyrics on Rap Genius

Meaning

A ghetto twist on the famous poem The Night Before Christmas which begins:

Twas the night before Christmas when all thro' the house
Not a creature was stirring, not even a mouse

A Tec-9 is a semi-automatic handgun.

Tec-9’s were very popular among inner city gangs due how cheap they were to get a hold of, and how easily they can be modified into full-auto.
