How would one accidentally invite someone to a wedding?

Well, just make some casual conversation about it first then move the conversation to what she thinks about being going to weddings (unless she tells you what she thinks about it first) depending on what she says if you get a good feeling from it ask her joining you "accidentally".

Also if she's the type that likes to make fun of weddings you could always "accidentally" ask her if she wants to make fun of it with you.


Sorry if this didn't help with the wording you're looking for.
