I recently spent a weekend in Las Vegas which involved heavy drinking and shenanigans. One thing I made sure to do, was not to post anything online while I was drinking. Vegas is one of those places that if you're celebrating a birthday, there's a good chance drinking will be involved. No doubt it was a blast, but if you're accustomed to posting info/pictures online, Snapchat is the way to go.
Similar to tattoos, posting something online while drunk probably wasn't a good idea and it never really goes away no matter how hard you try. Snapchat luckily "disappears" after a set amount unless somebody snaps a screenshot, so you're never really safe unless you just refrain from posting.
My group and I posted photos of our experience such as this:
Post your experience without visuals of heavy drinking or blurry photos that can infer your bad choices. Otherwise, Snapchat, it's ever so slightly safer.
