Get the Dinner Daddy mug.
While in a long term relationship the boyfriend becomes friendly with the girlfriends parents, upon breakup of the relationship and even stronger bond forms between the boyfriend and the girls father to a degree that the boy moves in with the father and commences a non-sexual relationship where upon the father looks after his daughters ex boyfriend as if he where his own son(the son he never had).

The father provides home cooked meals which are frozen onto a serving dish for the exboyfriend to take to work.
Worker 1: "whats with greg and those frozen meals"

Worker 2: "Greg still lives with his ex girls dad....and he cooks Gregs meals for work"

Worker 1: "what? like a dinner daddy or sumthin?"
