I won't be changing my last name so it makes that a bit more complicated. I have a friend who mentioned they're talking about combining each of their last names into a new one, and while we won't be doing that either, I thought about using a funny mashup for a hashtag. The funny one we came up with would be Twinke, pronounced like the junk food, Twinkie!
All I've got are #TeamTwinke or #TwinkeWedding which seem so boring! So I'm currently looking for fun suggestions!
