Shot caller
If I ever see anyone using one of those I’ll never believe he/she’s a real drinker. The main purpose of this gadget is to count time and actually tells you when you should drink your next shot of whatever poison you’re using. I bet you big time that even if you’re actually following its timer this is not gonna last for long. People tend to get very free minded after the third shot (like you don’t know it) and I don’t think this gadget can withstand the question “who/what are you to tell me when to drink” (especially when it’s followed with a hit). And even if the Shot Caller lasts that one big drinking night and doesn’t get smashed I’m not sure it’s gonna be “invited” to the next party. I consider this thingy totally useless except maybe if it’s used in drinking games and everyone else is so drunk they can’t really count “one, two, three, drink”. Or if you wanna play a joke on someone and hint them that they’re drinking too much (or less) just buy them this thing as a present (don’t expect it to be used though and mind that they may take this seriously). But overall, gentleman and ladies, instead of wasting your drinking money on unnecessary things why don’t you just spend them on what they’re purposed for (any doubts what I’m talking about?).
