Let the good times roll since it is your Birthday and all. Since you really do let those good times roll, we think it's appropriate to dub this holiday your "Happy BARFDAY!". Everyday can be your Barfday, it's all about whenever you want it to be. Fill this awesome pilsner cup with the beverage of your choice and Barf all over! The cool, hypnotic lighting comes in three modes: super flash, smooth flash, and steady light. One lighting mode for each of your Barfday stages. We suggest you stick with the steady mode for last because you're gonna be a bit tipsy as it is. You'll probably even try to use the Cup as a flashlight... we've seen it happen. These Cups even look good when everyone at the party has one. It definitely confirms the fact that no one's getting out of this without a hangover.
