Beverage shotgunning drinking apparatus

1. An apparatus comprising:

a body shell including an outer wall, a proximate end, a distal end, a passage, and a trigger opening;

a piercing tube slidably positioned within the passage of the body shell, the piercing tube including:

a first flange;

a proximate end including a piercing element with a central opening, the proximate end including a first diameter adjacent to the piercing element;

a distal end with a second diameter, the distal end including a drinking spout with a third diameter, wherein the first diameter is smaller than the second diameter, and wherein the second diameter is smaller than the third diameter; and

a drink passage between the central opening of the piercing element and the drinking spout; and

a trigger latch rotatably coupled to the outer wall of the body shell and operable to extend through the trigger opening to abut the piercing tube and maintain the piercing tube in an armed position, wherein the trigger latch abuts the first diameter of the proximate end of the piercing tube and the first flange of the piercing tube when the piercing tube is in the armed position.

2. The apparatus of claim 1 , further comprising a compression spring coupled to the body shell and the piercing tube, the compression spring providing tension when the piercing tube is in the armed position to bring the piercing tube into a can engagement position.

3. The apparatus of claim 1 , wherein the piercing tube includes a whistle port.

4. The apparatus of claim 1 , further comprising a can seal attached to the proximate end of the body shell, the can seal including a central opening sized to admit the piercing tube when in a can engagement position.

5. The apparatus of claim 1 , wherein the body shell includes a can engagement member on an outer wall of the proximate end of the body shell, the can engagement member including a curvature sized to engage a lower rim of a beverage can.

6. The apparatus of claim 5 , wherein the curvature of the can engagement member is further sized to engage a lip of a bottle cap and the proximate end of the body shell is configured to abut a top face of the bottle cap.

7. The apparatus of claim 1 , further comprising a key ring attachment coupled to an outer wall of the piercing tube to maintain the piercing tube in a stowed position, the key ring attachment abutting the distal end of the body shell and the drinking spout of the piercing tube.

8. The apparatus of claim 1 , wherein the piercing tube further includes internal ribs positioned in the drink passage.

9. The apparatus of claim 1 , wherein the trigger latch abuts the second diameter of the distal end of the piercing tube when the piercing tube is in a can engagement position.
