Play on the word "carburetor". Any device used to blow smoke (usually marijuana) through to filter and reduce/eliminate the smell in order to evade detection. Usually constructed by stuffing an empty toilet paper tube or paper towel tube with scented dryer sheets, then capping one end with a folded dryer sheet which is held in place by a rubber band.
My upstair neighbors are awake. Blow your smoke through the spoofalator!
My parents will be home in a couple hours. We should use the spoof just to be safe.
