A Gack is any item (other than a bottle opener) which is used to open a beer bottle. This applies only to bottles filled with beer. Soda, juice, de-alcoholized beer etc. do not apply. It must also not be a screw-off bottle. Due to the skill involved, a person who is rather adept at using various items to open a beer is referred to as a Gacksmith.
My buddy Todd is a real Gacksmith. He can make a Gack out of anything!
