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.

A stretched wide pussy that looks like she accidentally spilled a warm pie all over her lap. It is could also be used as a vacuum cleaner to suck up the entire universe if needed. Anything that fucks that Gack most likely be terminated from inside. Watch out because once you go Gack you don't come back.
