No one claims to be a Grumpy, but every group has one. No matter what is going on in her life, she is swamped and stressed, and you never know what will set her off. After two drinks, you may find Grumpy arguing with a bartender, or maybe her feet hurting and there's nowhere for her to sit. Whatever it may be, at some point in the night, she’s going to get pissy and will not hesitate to let everyone know about it. Sometimes more alcohol solves this problem, but it’s a fine line because additional booze can turn a Grumpy even Grumpier. Fruity drinks are your best option for Grumpy. No matter what, keep her away from Jager bombs or tequila.
