A endorsement from your spouse granting you permission go out with your friends

Usage is as follows :

Friend : "Hello...?"
Me : "hey man, this Friday... [person1] and [person2] are asking us out..."
Friend : " oh.... lemme check....."
(muffled sounds of talking ensue...)
Friend : " erm.... I don't think i can join you guys.....sorry..."
Me : "oh.... Visa ?"
Friend : " Yea..."
Me : "Its ok... we'll try next time..."
Friend : " Yea..."

Of course , the person in question has the right to defy the Visa rule and still go out anyway...
but most times, things get ugly after that...so its usually not worth it...
