What does “it’s giving wifey” mean?

So, I’m getting married soon and looking for some wedding related things. While I’m shopping I keeping coming across shirts and items that say “it’s giving wifey” on them…. Maybe I’m just having a super blonde moment but that statement makes no sense to me. Is this from something? Anyone know what it means? Lol.

I googled it and got nothing so I figured maybe some of you might know 🤷‍♀️
