A form of hazing that involves throwing a lower classman into a garbage can to amuse Seniors and Juniors.
A group of Seniors finds a Freshman and picks him off his feet. They then precede to take said Freshman and throw him in the trash can, thus "canning" him. Generally this is accompanied by shouts of protest from the victim and laughter by everyone else.
Occasionally said hazing can result in a fist fight.
