The act of driving down the street and hanging out of the window, while whirling a present into the recipients yard shouting (in a Santa like tone) "Merry Christmas!". Drive-by Christmas.
Katie: Brian's whole family is out there!
Chris: Ok... (while sitting on the edge of a window holding onto the sway bars getting ready to huck a present into the yard)
The present lands side up in a foot of snow.
