If ‘Wedding Crashers’ taught us one thing, it’s that weddings to which we aren’t invited are far superior to those which we’re required to attend. If it taught us anything else, it’s that crashing weddings is almost a full time job. It involves a ton of recon work.

Thankfully crashers now have the Crash Corsage app to do all the leg work. The app promises to show users nearby wedding receptions and help them fit in by explaining the dress code and even filling users in on factoids about the happy couple, including how they met. You can even compete against fellow crashers by completing the app’s challenges.

Rule #456 of wedding crashing – let an app do most of the work for you. Rule #23 – avoid the bridesmaid with the STD. If only an app could help you with that.
