Shotgun Daddy

The overprotective father of your new girlfriend. When you go to pick her up from her house, you will always see him sitting on the porch with a loaded shotgun in his lap and an unblinking stare that DARES you to make his little girl cry.

She's got a shotgun daddy. I went to pick her up to go to the movies and he was out on the porch loading a shotgun and looking at me.
