baking something sweet and delicious at another person's house, then after eating your fill, leaving all of the remainder. Meaning you then do not have a tummy ache from eating too many sweets and they, inevitably, do.
" Oh wow, I came home today and this girl I've been seeing baked an entire plate of cookies, then just left. They were delicious, but now my stomach hurts something fierce. I didn't realize she was cookie bombing me!"
