A fake wedding, the ultimate punchline of being engauged
. Most likely an overblown party where the hosts/hostesses are audacious enough to ask for wadding presents in the hopes their friends would just play along and give them a fake wedding in case they never have a real one.
"So we've picked a date for the wadding, and we're registered at Bed Bath and Beyond."
"Did you get your wadding invitation? It's a black tie affair."
"Our wadding is going to be so beautiful...and full of wine and naughty pictures"
"Did you hear, Paul is doing the catering for our wadding?"
