Hubsnad
A hubsnad is someone you are in a relationship with and you mutually agree that you would at some point get married. Instead of saying husband, you can say a different version to show your boyfriend how much you love him by reminding him that you'd like to stay with him.
Happy boyfriend 1- 'I love you hubsnad <3'
Happy boyfriend 2- 'I love you too'
Happy boyfriend 2- 'I love you too'
