Superglue that one

Signed, sealed, and made a permanent deal. You might not even realize it should be that permanent until someone else points it out to you.

Bill: idk dude first started to ignore her and flirt with other girls and then she shoved me in a closet and gave me a blowie.

Mike: wow man it sounds like you need to superglue that one.

Kate: First we were just fooling around and the next thing I know, my vajazzle ring came undone and got lost in the abyss.
Sarah: oh girl… sounds like you need to superglue that one.
