G mom
A mom who's so hot you'd rather eat a moldy sock than not touch her. She can be your mom, your dad's mom, or even a hot dog lady who knows your secrets.
My G mom is the reason I skipped school to flirt with her at the grocery store.
My dad's G mom gave me a wink that made me blush like a tomato.
My G mom once told me she'd rather fight a bear than not kiss me.
